The problem is to not give a warning when the string isn't meant as a
connection name at all, but as a libpq conninfo string (which can
perfectly reasonably run to more than 63 characters). Most if not all
of the dblink functions will accept either.
Perhaps a reasonable compromise is to issue the truncation warnings when
an overlength name is being *entered* into the connection table, but not
for simple lookups.
