The equivalent of SHOW TABLE foo; in pg would be:

\d foo

Note that there is no ; at the end of that command.

I'm not sure what's equivalent to SHOW DATABASE.

just \d

In psql:

\d
\l
\?


to show:
tables
databases
other backslash commands

erm, sorry, if you wanna see all the databases you can always:

SELECT datname FROM pg_database;

A SWAG would be \d, \di, and \dv.  Tables and sequences, indexes, and
views.

You cannot do that in postgres - it can only see tables in the database you are currently connected to.
7.3 has notion of schema though - that lets you have tables with the same names in the same database, but different
'schemas'.

I hope, it helps..
