Short Description
BLOB (lo type) objects could not be restored
Long Description
Hi :)
Problem appeared in POSTGRESQL 7.2b3 CVS distribution
After creating a table containing BLOB (lo type) column and filling it in an error
occured restoring this table using "pg_restore":
ERROR: Unable to identify an operator '=' for types 'oid' and 'lo'
You will have to retype this query using an explicit cast
Using Postgres 7.1.3 - there is no such error :(, but I need 7.2
because there are other fixes in it and I need them.
Please, see example:
Sample Code
-- user root
-- in postgres 7.2.b3 directory
./configure
./gmake
./gmake install
chmod -R 777 /usr/local/pgsql
-- user postgres
cd /usr/local/pgsql/bin
./initdb -D /usr/local/pgsql/data
-- ACTION: change access permissions in /usr/local/pgsql/data/pg_hba.conf to allow
access
./postmaster -D /usr/local/pgsql/data -i &
./createdb test
./psql -f test1.sql test
>-- test1.sql contains:
>
>CREATE TYPE lo (
> internallength=4, externallength=10,
> input=int4in, output=int4out,
> default='', passedbyvalue
>);
>
>CREATE TABLE "tb_snimki" (
> "egn" varchar(10) NOT NULL,
> "img" lo
>-- CONSTRAINT "snimki_pkey" PRIMARY KEY ("egn")
>);
-- ACTION: After this I inserted 1 small BLOB object (10K) in "tb_snimki"
-- from another PC with "egn" = "1234"
./pg_dump -b -Fc test > dump1.bin
./dropdb test
./createdb test
./pg_restore -v -Fc -d test dump1.bin
-- RESULT:
pg_restore: connecting to database for restore
pg_restore: creating TYPE lo
