PostgreSQL version: 9.2.1
Operating system: Ubuntu 12.04.1 LTS + Debian 6 (both x86_64
Description: =
I had a problem with missing rows in a resultset when using WHERE .. IN
after upgrading to 9.2.0. I was about to file a bug report when I found out
that verion 9.2.1 was just released to address the index visibility issue. =
I then upgraded to 9.2.1 and followed the instructions for vacuuming and
rebuilding indices
(http://wiki.postgresql.org/wiki/20120924updaterelease#Steps_for_Users_of_P=
ostgreSQL_9.2).
I still missed rows in the resultset. I ended up downgrading to 9.1.5 and it
works just fine without missing rows. =
