#55931: postgresql91 @9.1.24_2: "port select" creates invalid links

Component:  ports   |    Version:  2.4.2
 Keywords:          |       Port:  postgresql91
--------------------+--------------------------
 When selecting the postgresql91 port, some links created in /opt/local/bin
 are missing or wrong.

 E.g.:
 {{{
 $ sudo port -d select --set postgresql postgresql91
 }}}
 output (wrong):
 {{{
 ...
 DEBUG: ln -sf /opt/local/lib/postgresql91/bin/pg_resetxlog
 /opt/local/bin/pg_resetwal
 ...
 }}}

 Correct output would be:
 {{{
 ...
 DEBUG: ln -sf /opt/local/lib/postgresql91/bin/pg_resetxlog
 /opt/local/bin/pg_resetxlog
 ...
 }}}

 It seem to me that the file

 /opt/local/etc/select/postgresql/postgresql91

 contains a wrong number of lines consisting of a single "-" character. I
 attached a corrected version of that file which works correctly for me.

 My OS is macOS High Sierra.
