The <productname>PostgreSQL</productname> Global Development Team provides
|
|
the <productname>Postgres</productname> 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 <productname>Postgres</productname>
|
|
support team since November, 1996, is not aware of
|
|
any problems in the <productname>Postgres</productname> code base related
|
|
to time transitions around Jan 1, 2000 (Y2K).

</para>

<para>

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 <productname>Postgres</productname>. 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
|
|
<ulink url="http://www.postgresql.org/docs/user/datatype.htm">User's Guide</ulink>
|
|
in the chapter on data types.
|
|
For two-digit years, the significant transition year is 1970, not 2000;
|
|
e.g. <quote>70-01-01</quote> is interpreted as <quote>1970-01-01</quote>,
|
|
whereas <quote>69-01-01</quote> is interpreted as <quote>2069-01-01</quote>.

Any Y2K problems in the underlying OS related to obtaining "the
|
|
current time" may propagate into apparent Y2K problems in
|
|
<productname>Postgres</productname>.
