Dear all,
Is there a way to efficiently perform OR conditions across multiple
joins?
For example, I have the following statement:
SELECT RECORD.id
FROM RECORD
left join string
ON string.record_id = RECORD.id
AND string.layout_id = 6
left join DATE

I should have said
Dear all,
I'm performing a query with many joins, with a WHERE condition on the
"root" table. As far as I am aware, each join is indexed, as is the

conditional indexed values, and then "adding on" the relevant indexed
data.

Dear all,
I'm setting up hot backups on my database server. As such, I'd like to set up a
Postgres user that has access to only pg_start_backup and pg_stop_backup.
I'm unable to work out how to do this with the various GRANT options. Can
someone
