Hello,
In the init-script contained in the RPMs downloadable from the PostgreSQL
site (I checked the one for Fedora), an explicit locale is set before
running initdb. - And the explicit locale is not "C".
This means that a PostgreSQL installation will not use indexes for LIKE
queries (I just ran into this). See
http://www.postgresql.org/docs/faqs/FAQ.html#4.8
I suggest that the init-script be rewritten so that LANG and LC_ALL are
unset before initdb is run (which happens the first time PostgreSQL is
started after the RPM-based installation).
