logging dbname

So far I have a regression check run that generates a postmaster log that looks like this:

LOG: database system was shut down at 2003-08-02 16:39:48 EDT
LOG: checkpoint record is at 0/9A0530
LOG: redo record is at 0/9A0530; undo record is at 0/0; shutdown TRUE
LOG: next transaction id: 534; next oid: 17139
LOG: database system is ready
[db:regression] ERROR: group "regressgroup1" does not exist
[db:regression] ERROR: value too long for type character(1)
[db:regression] ERROR: value too long for type character(4)
.
.
.
[db:regression] NOTICE: drop cascades to table c1
[db:regression] NOTICE: drop cascades to constraint p1_a1 on table c1
[db:regression] NOTICE: drop cascades to table foo column f2
LOG: received smart shutdown request
LOG: shutting down
LOG: database system is shut down

At the moment it's forced, so the next thing would be to make it a GUC variable (log_dbname?).

Thoughts on format, location of name, etc?

cheers
