In 7.1.3, you can do it by updating the row in pg_database and then
restarting the postmaster:
$ psql template1
...
template1=# \l
List of databases
Database | Owner | Encoding
-----------+----------+-----------
junk | olly | SQL_ASCII
...
template0 | postgres | SQL_ASCII
template1 | postgres | SQL_ASCII
(8 rows)
template1=# update pg_database set datname = 'rubbish' where datname =
'junk';
UPDATE 1
template1=# \l
List of databases
Database | Owner | Encoding
-----------+----------+-----------
rubbish | olly | SQL_ASCII
...
template0 | postgres | SQL_ASCII
template1 | postgres | SQL_ASCII
(8 rows)
template1=# \c rubbish
FATAL 1: Database "rubbish" does not exist in the system catalog.
Previous connection kept
template1=# \c junk
FATAL 1: Database "junk", OID 44062648, has disappeared from
pg_database
Previous connection kept
template1=# \q
$ sudo /etc/init.d/postgresql restart
Password:
Restarting PostgreSQL database: postmaster

$ psql template1
...
template1=# \c rubbish
You are now connected to database rubbish.
rubbish=# \c junk
FATAL 1: Database "junk" does not exist in the system catalog.
Previous connection kept
rubbish=#
An alternative method would be to dump everything with pg_dumpall and
then edit the dump to change the database name.
