Michael-

	As I mentioned earlier, your solution worked great.  I am a bit
puzzled about the syntax that is created by my old method, using "pg_dump
-D -u -a".  I wonder why it creates "create sequence ..." commands instead
of "update sequence ..."?

	The reason I was originally using "-a" to begin with was that I
wanted to seperate the data entry from the table creation step.  So, the
idea was that I would have a nice hand editted script to make all my
tables, then the "-a" output of pg_dump would fill the database with data.

	As I said, your solution works, thanks, I'm just puzzled why my
way didn't.

	Later, Jon
