mysql command equivalents?

At the continuing urging of an acquaintance (and with the uncertainty
around Oracle's acquisition of Sun) I'm trying to give PostgresSQL a
try, but the difference in commands is seriously frustrating.

Is there a nice single table somewhere listing MySQL equivalents,
e.g. "USE database" == ? My google-fu is failing me. (And even the
docs don't seem to have anything for that particular example.)

A cheat sheet would speed things up immensely.

TIA!
