Re: Backup Compatibility between minor versions.

Thanks for the response Doug. I am frightened to upgrade the linux
machine to 8.0.3 at the moment because the server is live and I want to
make sure that 8.0.3 will fix it. I have extracted the relevant parts of
the restore as follows:

1. The restore command

    pg_restore.exe -i -h 10.202.6.195 -p 5432 -U postgres -d export -l
    "backup9.backup"


2. The first error in the output.

    pg_restore: creating FUNCTION dex_init(text)
    pg_restore: [archiver (db)] Error while PROCESSING TOC:
    pg_restore: [archiver (db)] Error from TOC entry 25; 1255 72303
    FUNCTION dex_init(text) postgres
    pg_restore: [archiver (db)] could not execute query: ERROR:  unsafe
    use of INTERNAL pseudo-type
    DETAIL:  A function returning "internal" must have at least one
    "internal" argument.
        Command was: CREATE FUNCTION dex_init(text) RETURNS internal
        AS '$libdir/tsearch2', 'dex_init'
        LANGUAGE c;

This was intalled to a clean database on XP with no tsearch2 installed.
To me it looks as if there has been some modification in the use of
INTERNAL from 8.0.1 to 8.0.3.

FYI here is a dump of that tsearch2 function:

    CREATE OR REPLACE FUNCTION dex_init(text)
      RETURNS internal AS
    '$libdir/tsearch2', 'dex_init'
      LANGUAGE 'c' VOLATILE;
    ALTER FUNCTION dex_init(text) OWNER TO postgres;


Is it possible to change that function to be compatible with both 8.0.1
and 8.0.3 - or am I looking in the wrong place?
