Re: Query plan changes after pg_dump / pg_restore - Mailing list pgsql-performance

Thanks... have notified our sys admin of that so he can make the correct
changes.

It still doesn't explain the difference in query plans though?

I mean, it's the same database server the two instances of the same
database is running on.
One instance (the live) just insists on doing the seq scan of the 50k
records in Price_Tbl and the 6.5k records in SCT2SubCatType_Tbl.
Seems weird....

Cheers
