[BUGS] Index Ignored Due To Use Of View
PostgreSQL 8.3.14 OS: Linux Redhat 5.4 Note: I have used the same subject for this email taken from an email: Posted 2011-02-24 13:29:22-08 by "David Johnston", because this seems to be a very similar observation. Bug/Problem Summary: We are using a simple query based on a simple view and the query optimizer is not choosing an index. The same query without the view is using an index. The same query on an almost identical view, but having either removed a single column which was generated via a function call or replace the function call with equivalent SQL, then the query optimizer is choosing an index. Other notes: We observe the same behaviour on two separate databases running on separate servers (both the same version). The genetic query optimizer settings are all on defaults for these versions. Details; With the following view: CREATE OR REPLACE VIEW vu_tbl_news_web AS SELECT n.id, n.id_cmpy, n.id_news, n.id_newshdline, n.s_origcmpyname, n.s_hdline, n.s_news, n.b_amend, n.b_replace, n.dt_publish, n.tsv_hdline, n.tsv_news, n.b_hasorigdoc, (SELECT h.s_hdline FROM tbl_newshdline h WHERE h.id = n.id_newshdline LIMIT 1) AS s_hdlinetype, get_cmpyname(n.id_contrib) AS s_provider FROM tbl_news n WHERE n.dt_publish IS NOT NULL; Query: SELECT n.id, n.id_cmpy, n.s_origcmpyname, n.s_hdline, n.dt_publish FROM vu_tbl_news_web n ORDER BY n.dt_publish DESC LIMIT 25 Analyse produces: Limit (cost=180017.37..180017.43 rows=25 width=80) -> Sort (cost=180017.37..180110.54 rows=37267 width=80) Sort Key: n.dt_publish -> Subquery Scan n (cost=0.00..178965.72 rows=37267 width=80) -> Seq Scan on tbl_news n (cost=0.00..178593.05 rows=37267 width=1152) Filter: (dt_publish IS NOT NULL) SubPlan -> Limit (cost=0.00..4.29 rows=1 width=22) -> Seq Scan on tbl_newshdline h (cost=0.00..4.29 rows=1 width=22) Filter: (id = $0) Although the number of rows (37k) is small, there is a lot of data in some of the columns so, with a seq. scan its taking nearly 2 seconds. Compared to 16ms when using an index. Now if I perform the same query without using the view, such as: SELECT n.id, n.id_cmpy, n.s_origcmpyname, n.s_hdline, n.dt_publish FROM tbl_news n WHERE n.dt_publish IS NOT NULL ORDER BY n.dt_publish DESC LIMIT 25 Analyse produces: Limit (cost=0.00..21.34 rows=25 width=73) -> Index Scan Backward using tbl_news_publish1_key on tbl_news n (cost=0.00..31807.05 rows=37267 width=73) Finally I discovered that if I remove a column from the view, that is generated via a function, then all works as expected? CREATE OR REPLACE VIEW vu_tbl_news_web3 AS SELECT n.id, n.id_cmpy, n.id_news, n.id_newshdline, n.s_origcmpyname, n.s_hdline, n.s_news, n.b_amend, n.b_replace, n.dt_publish, n.tsv_hdline, n.tsv_news, n.b_hasorigdoc, (SELECT h.s_hdline FROM tbl_newshdline h WHERE h.id = n.id_newshdline LIMIT 1) AS s_hdlinetype FROM tbl_news n WHERE n.dt_publish IS NOT NULL; SELECT n.id, n.id_cmpy, n.s_origcmpyname, n.s_hdline, n.dt_publish FROM vu_tbl_news_web3 n ORDER BY n.dt_publish DESC LIMIT 25 Analyse produces: Limit (cost=0.00..21.34 rows=25 width=73) -> Index Scan Backward using tbl_news_publish1_key on tbl_news n (cost=0.00..31807.05 rows=37267 width=73) The definition of the function used is: CREATE OR REPLACE FUNCTION get_cmpyname(integer) RETURNS citext AS $BODY$ DECLARE idcmpy ALIAS FOR $1; sumb citext; sres citext; BEGIN SELECT INTO sumb, sres s_umbname, s_name FROM tbl_cmpy WHERE (id = idcmpy) LIMIT 1; IF length(sumb) > 0 THEN sres := sumb || ' - ' || sres; END IF; RETURN sres; END $BODY$ LANGUAGE 'plpgsql' VOLATILE STRICT SECURITY DEFINER COST 100; I also noted that if I replace the function call in the view with equivalent SQL: (SELECT (CASE WHEN length(c.s_umbname) > 0 THEN c.s_umbname || ' - '::citext || c.s_name ELSE c.s_name END) AS s_cmpyname FROM tbl_cmpy c WHERE c.id = n.id_contrib LIMIT 1) AS s_provider the problem also goes away.

Also, it's bad practice to do order by/limit in the new definition like that. Leave them off, and do it in the calling query. I would write your function like this: CREATE OR REPLACE FUNCTION get_cmpyname(integer) RETURNS citext AS $$ SELECT CASE WHEN length(s_umbname) > 0 THEN s_umbname || '-' || s_res ELSE '' END FROM tbl_cmpy WHERE id = $1; $$ LANGUAGE sql STABLE STRICT; I took off the limit 1 because you probably don't need it. merlin -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs

[BUGS] BUG #5942: pg_trgm.sql has cyclic dependency on type gtrgm creation
The following bug has been logged online:
Bug reference: 5942
Logged by: Arthur Nascimento
Email address: tur...@gmail.com
PostgreSQL version: 9.0.3
Operating system: Linux
Description:pg_trgm.sql has cyclic dependency on type gtrgm creation
Details:
When creating the gtrgm type, it depends on gtrgm_{in,out}. These functions
also depend on the type, so there is a cyclic dependency on creation of the
type.
The command psql -f sharedir/contrib/pg_trgm.sql crashes for me accusing
this error.
According to the CREATE TYPE documentation, this can be solved by adding a
"CREATE TYPE gtrgm;" line before the functions are defined. This solution
worked locally for me by including that command between lines 40 and 41 of
the file.
A snippet of the offending code of contrib/pg_trgm.sql, lines 40 to 55:
-- gist key
CREATE OR REPLACE FUNCTION gtrgm_in(cstring)
RETURNS gtrgm
AS '$libdir/pg_trgm'
LANGUAGE C STRICT;
CREATE OR REPLACE FUNCTION gtrgm_out(gtrgm)
RETURNS cstring
AS '$libdir/pg_trgm'
LANGUAGE C STRICT;
CREATE TYPE gtrgm (
INTERNALLENGTH = -1,
INPUT = gtrgm_in,
OUTPUT = gtrgm_out
);

Crashes how? That script works fine for everybody else. You might get
some notices but not a crash.

The following bug has been logged online: Bug reference: 5944 Logged by: Nathan Davalos Email address: n.dava...@sharedmarketing.com PostgreSQL version: 9 Operating system: Windows XP/2003 Description:COPY FROM doesn't work with international characters Details: I'm trying to load a tab delimited text file with COPY FROM under version 9. create table tmpintermediate ( AcNumber character varying(20), AcName character varying(50)); SET CLIENT_ENCODING TO 'WIN1251'; copy tmpintermediate from 'thefile.txt'; Sample contents of thefile: 230002 Alto Desempeño, S.A. De C.V. When using WIN1251 or WIN1252 I get nothing in the second field, it just ignores the data. Same thing for LATIN-1. When using UTF8 for client encoding I get this message: ERROR: invalid byte sequence for encoding "UTF8": 0xf16f2c20 CONTEXT: COPY tmpintermediate , line 1 Not sure what the problem is, I assumed encoding the database as UTF8 would just take any character. Inserting the data with an insert statement works perfectly normal. Is it something I'm doing wrong with COPY FROM? The database is UTF8, in 8.3 we were using WIN1252 for the database encoding, but when we migrated to 8.4 everything was forced to UTF8 regardless of what the locale was specified during install using pg_dumpall to migrate the data, so I just left things as UTF8. Not sure how to proceed with this one. We create all our databases using a customized template datatabase (we leave the ones that install with postgresql intact and untouched). The copy commands are being issued by pgadmin3 if that makes any difference. That and we use MicroOlap's PosgresDAC components for Delphi. -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs

Yeah, that's intentional. If the planner flattens a view that has a function in its output list, things get a lot less predictable about when the function will be called. For a volatile function, that can matter a lot. We used to flatten such views anyway, but we got enough complaints that we changed it. http://archives.postgresql.org/pgsql-committers/2006-08/msg00358.php regards, tom lane -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs

[BUGS] BUG #5943: jdbc client doesn't omit pg_toast_temp tables from schema views
The following bug has been logged online: Bug reference: 5943 Logged by: Daniel Ceregatti Email address: dan...@ceregatti.org PostgreSQL version: N/A Operating system: N/A Description:jdbc client doesn't omit pg_toast_temp tables from schema views Details: In the file org/postgresql/jdbc2/AbstractJdbc2DatabaseMetaData.java is the query: sql = "SELECT nspname AS TABLE_SCHEM FROM pg_catalog.pg_namespace WHERE nspname <> 'pg_toast' AND nspname !~ '^pg_temp_' ORDER BY TABLE_SCHEM"; Using Data Tools Platform in eclipse I was able to see all the pg_toast_temp_XXX schemas in the schema view. Using postgresql-9.0-801.jdbc4.jar Please note that RhodiumToad in #postgresql on irc.freenode.org actually discovered this based on a conversation he, ojacobson, and I had, and I'm simply reporting what he discovered.
