Hello all.

I have been lurking here for a bit and the MERGE topic (on [HACKERS]) caught
my eye, so I had a go at implementing a basic version of MERGE-on-INSERT in
pl/pgsql.  It is attached below, and any comments are welcome.  I find it
useful on "status" type tables, though it is not very nice when there are
many clients (table locking to avoid race conditions).

Hope someone will find it useful!
