upgrade from 7.1.2 to 7.1.3 and uh, where are my databases?

I upgraded from 7.1.2 to 7.1.3. Upon starting 7.1.3, I tried to use psql
to access my databases. But whether I use psql -U foo, or psql -d foo, I
am told that:

psql: FATAL 1: Database "foo" does not exist in the system catalog.

When I examine /usr/local/pgsql/data, it certainly looks as though my
databases are still on the disk. How do I get postgresql to recognize them?

More details:

Since I was upgrading from 7.1.2 to 7.1.3, I didn't bother (my mistake)
backing up the system. I didn't call initdb explicitly. I did:

./configure --with-x --with-tcl
make
make check
make install

I am worried that the make check may have done an initdb.

Would initdb wipe out my existing databases?

How do I get my existing databases to be reentered into the system catalog?

Thank you,

Jerry Asher
