Roger that - I did and installed 7.0.2 this morning. As usual the
build went fine and to my amazement the versions of DBI and DBD
I had in place seem to work fine also! (It did take me awhile to
locate and install the pg man pages...but I got there.)

I do have a silly question tho: On RH 6.1 Linux the pg tarballs
that come from Lamar O. are 6.5.2. And they work fine - in fact
there is a command history function in psql that I like alot being
a bash user - even on FBSD and UnixWare.

Yet, I can't get command hx to work for 7.0.2 psql (on slackware 3.6).
Am I not seeing something obvious here?

TIA,
Tom Good
