I don't think it makes sense to add it here. One odd thing is that WITH can be used with non-SELECT statements, but we only document it in SELECT, which is odd. I think that is because the SQL standard only uses WITH with SELECT. -- Bruce Momjian http://momjian.us EnterpriseDB http://enterprisedb.com + As you are, so once was I.

Re: Global dict name is listed inconsistently
Yes, it does, thank you. Now it's clear why there are two different names.

Re: 25.3. Continuous Archiving : Unix examples with Windows-style variables %-$
These are special variables that PostgreSQL replaces regardless of operating system. Per the paragraph above the examples: Oops! Sorry. Should read more thoroughly before sending stupid comments on this excellent documentation! Thank you for taking the time to clarify. Mi
Re: Documentation does not cover multiple WITH in one query
Thank you. That is I am looking for. Never thought that 'WITH' syntax is described at 'SELECT'. Will be very helpful if this will be mentioned on this page: https://www.postgresql.org/docs/10/static/queries-with.html For an example: [ WITH [ RECURSIVE ] with_query [, ...] ] and with_query is shown as: with_query_name [ ( column_name [, ...] ) ] AS ( select | values | insert | update | delete ) For full syntax of `WITH` see https://www.postgresql.org/docs/10/static/sql-select.html Thanks. 24.08.2018, 23:30, "Bruce Momjian" : > On Wed, Aug 22, 2018 at 09:24:52AM +, PG Doc comments form wrote: >> The following documentation comment has been logged on the website: >> >> Page: https://www.postgresql.org/docs/10/static/queries-with.html >> Description: >> >> Hi.
