Re: [BUGS] pl/pgsql problem with search_path

[Eugene Chow]

Thanks. If I had only read the manual before posting. I solved it by  
using 'execute' instead of 'select into' since the search_path is not  
static in my system.

I think the problem is that the first time the function is called, it  
is
compiled and cached for later use.  At that time the function is bound
to the table oid, so even though you change the search path, the cached
copy still calls the old table.

If you exit psql and re-enter, or change the schema _before_ you call
the function for the first time, it should be fine.
This highlights another problem with our plpgsql function caching.

My plpgsql function seems to be ignoring search_path when looking for
the right table to select from. I'm running 7.3.4. Below is my test
code. Am I doing something wrong?
TIA, Gene Chow

test=> create or replace function getval() returns varchar as '
test'> declare val varchar;
test'> begin
test'>     select into val value from bar limit 1;
test'>     return val;
test'> end;' language 'plpgsql';
CREATE FUNCTION
test=> create table public.bar ( value varchar );
CREATE TABLE
test=> insert into public.bar values ('public value');
INSERT 4012748 1
test=> create schema foo;
CREATE SCHEMA
test=> create table foo.bar ( value varchar );
CREATE TABLE
test=> insert into foo.bar values ('foo value');
INSERT 4012754 1
test=> set search_path to foo, public;
SET
test=> select *, getval() from bar;
    value   |  getval
-----------+-----------
  foo value | foo value
(1 row)
test=> set search_path to public;
SET
test=> select *, getval() from bar;
     value     |  getval
--------------+-----------
  public value | foo value
(1 row)
