If the system-name field of a pg_ident.conf line is a regex containing capturing parentheses, you can write \1 in the user-name field to represent the captured part of the system name. But what happens if you write \1 more than once? The only reasonable expectation IMO is that each \1 gets replaced, but presently our code replaces only the first. Fix that. Also, improve the tests for this feature to exercise cases where a non-empty string needs to be substituted for \1. The previous testing didn't inspire much faith that it was verifying correct operation of the substitution code. Given the lack of field complaints about this, I don't feel a need to back-patch.
