Re: System Table Query

Thanks Stephan.  I've found the relevant pg_proc
entries now and am able to proceed.  Are there any
ancillary sources of information on the system tables
(other than the source, which is a bit too easy to get
lost in!) over and above what comes in the standard
documentation, which I find bit thin in this area for
my purposes?

Regards,
John Bell
