Is it possible to isolate logging for each individual database?
For example, lets say I have 3 databases: db1, db2, db3. And I want to
log db activity (statements, login/logout, etc..)  db1, db2, db3 like
$PGDATA/db1, $PGDATA/db2, $PGDATA/db3, respectively.

Currently everything is logged in $PGDATA/pg_log

TIA

I don't think you can do it in PostgreSQL itself.

I suggest this method:

  Configure PostgreSQL to log to standard output.

  When starting the postmaster, redirect standard output to a named
pipe.

  Before you start PostgreSQL, start up a perl script to read the named
pipe and write to appropriate logs.
