Thanks for the excellent description, Josh. And the reminder of the
performance list (it's existence somehow slipped from my mind).

Hi-
This is more just trying to understand what is going on under the hood of
pgsql. I have read through the archives that there is no difference between
index on char, varchar or text. I am wondering why? I understand all the
arguments about saving space but I am specifically asking about ind

lot of sql revisions to their application.
Thanks-Beth

Hi-
I can't figure out how to do this
I examine a table where I think that one attribute is an abbreviation of
another attribute.

I want something like
SELECT whatever FROM my_table WHERE long_name LIKE '%[the value of ABBR
