Обсуждение: Materialized View patch broke pg_dump
It looks like the recent matview patch broke pg_dump in a way, which make
it impossible to dump 9.1 and 9.2 databases.
it fails with
pg_dump: [Archivierer (DB)] query failed: ERROR: function
pg_relation_is_scannable(oid) does not exist
Looking into this issue, it seems the version check in getTables() of
pg_dump.c is wrong. Shouldn't the check be
if (fout->remoteVersion >= 90300)
{
}
since this is where pg_relation_is_scannable() is introduced?

Thanks

I noticed this morning that I am still getting failures on 9.0, 9.1 and
9.2 which cause my cross-version upgrade testing to fail for git tip.
For all I know this might apply to all back branches, but these are the
only ones tested for upgrade, so that's all I can report on reliably.
I'm chasing it up to find out exactly what's going on, but figured some
extra eyeballs would help.
cheers

The problem is that pg_dump is sending an empty query in versions less
than 9.3, and choking on that. Suggested fix attached - there's really
no reason to be doing anything re mat views in versions < 9.3.

This is the same problem that I reported in another thread.

The patch looks good to me.

Oh, I missed that. Yes, either of these would work.

I preferred Andrew's patch because it kept knowledge of this issue more localized. Pushed. Thanks to you both, and apologies for the error. Next time I do anything with pg_dump I will know better what constitutes decent testing. -- Kevin Grittner EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
