Hi Folks

I have a column for date which defaults to the ambigous 2005-1-1 format.

The documantation indicates how to change this to the unambigous Jan 1 2005, but the instructions aren't clear to me.

Any help will be appreciated.

Actually, if the year comes first, it is not ambiguous. It will always
be month-day if the year comes first. It's the

mm/dd/yyyy or dd/mm/yyyy that is the issue.

choose an index scan if your joining column's datatypes do not
match

Re: Dates

Oh yeah, right. You want to set your datestyle.

See:

Changing it once:
http://www.postgresql.org/docs/8.1/static/datetime-appendix.html

Changing it for a database:
http://www.postgresql.org/docs/8.1/static/sql-alterdatabase.html

Changing it for everything that doesn't override it:
http://www.postgresql.org/docs/8.0/static/runtime-config.html
