Mention of connection options - Mailing list pgsql-docs

I have applied the following documentation patch to mention that
libpgtcl's connection options are listed in libpq's manual page.  I also
fixed some libpq++ markup.

Hope it is OK.

       The following environment variables can be used to select default
!      connection parameter values, which will be used by PQconnectdb or
!      PQsetdbLogin if no value is directly specified by the calling code.
       These are useful to avoid hard-coding database names into simple
       application programs.
