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

Yes, the version you see when you start psql at the top is the psql
version. If you type 'SELECT version()', you see the server version.
8.1 will improve the psql display on startup.
