Re: pgbench - allow to store select results into variables

Yep.

I do not know why "git apply" sometimes complains. All is fine for me both 
with "git apply" and "patch".

Last time it was because my mailer uses text/x-diff for the mime type, as 
define by the system in "/etc/mime.types", which some mailer then 
interpret as a license to change eol-style when saving, resulting in this 
kind of behavior. Could you tell your mailer just to save the file as is?

Are you sure that you are using the compiled pgbench, not a previously 
installed one?

   bin/pgbench> pgbench -t 1 -f SQL/gset-1.sql
     SQL/gset-1.sql:1: invalid command in command "gset"
     \gset

   bin/pgbench> ./pgbench -t 1 -f SQL/gset-1.sql
     starting vacuum...end.
     debug(script=0,command=2): int 1
     debug(script=0,command=4): int 2
     ...

The intention is to test that gset & gcset work as expected in various 
settings, especially with combined queries (\;) the right result must be 
extracted in the sequence.

Because a pgbench scripts stops on the first error, and I wanted to test 
what happens with several kind of errors.
