I've restored template1 in v8.4, and created again the db where I will
be restoring v7.14 backup
newdb=# select proname,probin,pronamespace from pg_proc where
proname='plpgsql_call_handler';
proname | probin | pronamespace
---------+--------+--------------
(0 filas)
And in v10.10 (which is still an empty installation)
template1=# select proname,probin,pronamespace from pg_proc where
proname='plpgsql_call_handler';
proname | probin | pronamespace
----------------------+-----------------+--------------
plpgsql_call_handler | $libdir/plpgsql | 11
(1 row)
After restoring backup in v8.4:
newdb=# select proname,probin,pronamespace from pg_proc where
proname='plpgsql_call_handler';
proname | probin |
pronamespace
----------------------+----------------------------------------+--------------
plpgsql_call_handler | $libdir/plpgsql | 11
plpgsql_call_handler | /usr/lib/postgresql/8.4/lib/plpgsql.so
| 2200
(2 filas)
As you said, 2200 is public namespace/schema and 11 is pg_catalog.
At the beginning of the backup file I can find these sentences:
CREATE FUNCTION plpgsql_call_handler() RETURNS language_handler
LANGUAGE c
AS '/usr/lib/postgresql/8.4/lib/plpgsql.so',
'plpgsql_call_handler'; <-- I've changed this line to use the right path
to plpgsql.so library
CREATE PROCEDURAL LANGUAGE plpgsql HANDLER plpgsql_call_handler;
I guess these are the ones causing all of this. **What should be the
best way to handle this situation?** Remove these lines and create the
language explicitly when creating database? Or replace them with a
create language sentence? Maybe something else? My final goal is migrate
from 7.14 server to 8.4 server and after that (if I have an OK from the
boss) upgrade 8.4 to the latest version that I can use. Server uses
CentOS, and probably I won't be able to upgrade to v10 but I hope at
least 9.5/9.6 will be available.
