Description:

Dear all,
Pls. let me suggest the correction for the
https://www.postgresql.org/docs/17/auth-username-maps.html page.
It has the following sentence:
'
If the database-username field starts with a slash (/), the remainder of the
field is treated as a regular expression (see Section 9.7.3.1 for details of
PostgreSQL's regular expression syntax). It is not possible to use \1 to use
a capture from regular expression on system-username for a regular
expression on database-username.
'
It looks like 'to use a capture' has to be replaced by 'to capture'.
best regards
Alexey Shishkin

  1. Doc: clarify description of regexp fields in pg_ident.conf.

  2. In username-map substitution, cope with more than one \1.
