postgresql log parsing to report on user/db access

Is anyone aware of a quick solution for producing user/db access reports
from pgsql syslog format logs?

in other words, I have a bunch of lines such as:

> Apr 22 06:39:04 147283-db3 postgres[13252]: [1800-1] user=database1_remote,db=sqm_remote_database1 LOG: connection authorized: user=database1_remote database=sqm_remote_database1
> Apr 22 06:39:04 147283-db3 postgres[13252]: [1801-1] user=database1_remote,db=sqm_remote_database1 LOG: disconnection: session time: 0:00:00.01 user=database1_remote
> Apr 22 06:39:04 147283-db3 postgres[13254]: [1799-1] user=[unknown],db=[unknown] LOG: connection received: host=172.25.150.172 port=58088
> Apr 22 06:39:04 147283-db3 postgres[13254]: [1800-1] user=database1_remote,db=sqm_remote_database1 LOG: connection authorized: user=database1_remote database=sqm_remote_database1
> Apr 22 06:39:04 147283-db3 postgres[13254]: [1801-1] user=database1_remote,db=sqm_remote_database1 LOG: disconnection: session time: 0:00:00.02 user=database1_remote
> Apr 22 06:39:12 147283-db3 postgres[13259]: [1799-1] user=[unknown],db=[unknown] LOG: connection received: host=172.25.150.162 port=40768
> Apr 22 06:39:12 147283-db3 postgres[13259]: [1800-1] user=database3_remote,db=sqm_remote_database3 LOG: connection authorized: user=database3_remote
> Apr 22 06:39:12 147283-db3 postgres[13259]: [1801-1] user=database3_remote,db=sqm_remote_database3 LOG: disconnection: session time: 0:00:00.01 user=database3_remote
> Apr 22 06:39:16 147283-db3 postgres[13263]: [1799-1] user=[unknown],db=[unknown] LOG: connection received: host=172.25.150.69 port=37739
> Apr 22 06:39:16 147283-db3 postgres[13263]: [1800-1] user=database2_remote,db=sqm_remote_database2 LOG: connection authorized: user=database2_remote database=sqm_remote_database2
> Apr 22 06:39:16 147283-db3 postgres[13263]: [1801-1] user=database2_remote,db=sqm_remote_database2 LOG: disconnection: session time: 0:00:00.01 user=database2_remote
> Apr 22 06:39:18 147283-db3 postgres[13264]: [1799-1] user=[unknown],db=[unknown] LOG: connection received: host=172.25.150.69 port=37740

and I'd like to be able to generate weekly reports that provide rolled
up statistics on which user connected to which db, how many times, etc.

I've used pg_fouine for doing reporting on queries, but it doesn't
really deal with tracking user/db access.

Before I try to whip up something myself with perl or something, I
wanted to see if anyone's already done something similar.

thanks in advance--
