Greetings:

I have a scenario in which it would be quite convenient to mark about 20
existing columns in a table such that I can select those fields
programatically, based on my flag, for some specialized processing. What I am
trying to avoid is storing a list of columns somehere. Is there something like
a "user area" in the underlying tables that define a column that could be
safely utilized for this purpose?

I'm using PostgreSQL 8.3 on Red Hat.

TIA
