From the FAQ:
====================
1.14) Will PostgreSQL handle recent daylight saving time changes
in various countries?
PostgreSQL versions prior to 8.0 use the operating system's
timezone database for daylight saving information. All current
versions of PostgreSQL 8.0 and later contain up-to-date timezone
information.
====================
In this context, assuming we have applied the relevant OS patches
(RHEL, Debian, HPUX 11.11, 11.23), does the phrase "contain
up-to-date timezone information" mean that all 7.[234].x and 8.x
installations are prepared to properly handle the March 1, 2007
DST changes in the US? If not, what is needed?
TIA.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
