[SQL] add column if doesn't exist (fwd)

I figured pgsql-general would be a more appropriate forum for the
question below.

Subject: [SQL] add column if doesn't exist

Is there a way to check for the existence of a column in a table other
than, say, doing a SELECT on that column name and checking the output?

I'm basically looking to do an ALTER TABLE foo ADD COLUMN bar if bar
doesn't exist.

Thanks.

TIP 9: In versions below 8.0, the planner will ignore your desire to
       choose an index scan if your joining column's datatypes do not
       match
