I built an application last year which used the name "over" as the name
of a boolean field in one of the tables.
It was in regular use last year and worked fine.
I have been regularly taking backups with of this database with the
following command
pg_dump -Fc melindas_ball | gzip -9 > ball.s
Hi. Thanks for your reply.
I looked at the documentation for partitions - it is the case, right, that I
have to create the master table and the two partition tables (depending
on the value of rbscore) and then copy the records from the existing
table into the two partitions?

Many wrote that the functional programming 'fold' is a good model for
relational aggregate functions. I have a few difficulties with this:
1. fold doesn't offer any type of GROUP BY, which is an essential component
of aggregation.
2. I don't believe fold can handle things like AVG() or STDDEV().
I have a table with a lot of columns. One of the columns I want to alias so
have a query of:
select *, column as newname from mytable.
The problem is I now have column and newname in the results. I don't want
to select column by column. How can I do a select * but omit one?
Thanks!
