Hello,
finally the problem is solved. The problem was with locales.
I installed and initialised the database under cs_CZ, so Pg
recorded cs_CZ in all its configurations and startup scripts.
After that I changed /etc/sysconfig/i18n to use en_US locale as
system default.
And that was the problem. According to "ps axe" the postmaster was
running under en_US locales instead of cs_CZ as I expected.
So I changed /etc/sysconfig/i18n to use cs_CZ and everything is ok
from then. All indexes seem to be working fine and there are no problems.
But I would like to know why it was not started under cs_CZ when
all Pg config files specify cs_CZ and ~postgres/.bash_profile contains
export LANG="cs_CZ" and postmaster is run from it's rc script as
su -l postgres -s /bin/sh -c "/usr/bin/pg_ctl -D $PGDATA ...."
So I expected that cs_CZ will be used in this case. :-( GRrrrrr.
Ok now it's working, thank you all who helped.
