The PostgreSQL Global Development Team provides
the Postgres software code tree as a public service,
without warranty and without liability for it's behavior or performance.
However, at the time of writing:
The author of this statement, a volunteer on the
Postgres
support team since November, 1996, is not aware of
any problems in the Postgres code base related
to time transitions around Jan 1, 2000 (Y2K).
The author of this statement is not aware of any reports of Y2K problems
uncovered in regression testing
or in other field use of recent or current versions
of Postgres. We might have expected
to hear about problems if they existed, given the installed base and
the active participation of users on the support mailing lists.
To the best of the author's knowledge, the
assumptions Postgres makes about dates specified with a two-digit year
are documented in the current
User's Guide
in the chapter on data types.
For two-digit years, the significant transition year is 1970, not 2000;
e.g. "70-01-01" is interpreted as 1970-01-01,
whereas "69-01-01" is interpreted as 2069-01-01.
Any Y2K problems in the underlying OS related to obtaining "the
current time" may propagate into apparent Y2K problems in
Postgres.
Refer to
The Gnu Project
and
The Perl Institute
for further discussion of Y2K issues, particularly
as it relates to open source, no fee software.
