Comment(by edechaux):

 I know but backporting to 2.1 is very easy and postgis version not
 significant here.

 The issue is that postgresql parser does not handle two dots in a GUC
 parameter. From postgresql 9.2.4 sources in '''src/backend/utils/misc/guc-
 file.l''' :

 {{{
                 /* first token on line is option name */
                 if (token != GUC_ID && token != GUC_QUALIFIED_ID)
                         goto parse_error;
 }}}

 and


 {{{
 LETTER                  [A-Za-z_\200-\377]
 LETTER_OR_DIGIT [A-Za-z_0-9\200-\377]

 ID                              {LETTER}{LETTER_OR_DIGIT}*
 QUALIFIED_ID    {ID}"."{ID}

 [...]

 {ID}                    return GUC_ID;
 {QUALIFIED_ID}  return GUC_QUALIFIED_ID;
 }}}

 So the only dot a custom parameter should use is the one spliting the
 module identifier and name of the parameter, as seen
 [http://www.postgresql.org/docs/9.2/static/runtime-config-custom.html
 here].

 Please reconsider reopening this ticket.
