[postgis-users] Metadata (fgdc, etc)?

[Webb Sprague]

I am sorry if I missed it in my cursory search...

Is there a postgis (at least postgresql) specific way to store
metadata?  Any personal best practices?  A link would be fine.

(This makes me wonder about keeping track of the temporal validity of
either a table or a geometry, like when a city is busy subdividing and
annexing, but that is another story for another day.)

Thanks for all the help and the (to Refractions and developer
community) the great free product.
