Bug #162: refactoring of typenameTypeId() requires using different
function signatures with different PG versions.

Notably, on 9.1, it's used as
    typenameTypeId(NULL, txid_snapshot_typname)

Per refactoring commit:
http://git.postgresql.org/gitweb?p=postgresql.git;a=commit;h=35670340f57d78d6ab023b1fb42fd81339f85d4c

We were already detecting 1/2/3 parm versions of this function, so
all that's necessary is to add #ifdef to choose between them in
src/backend/slony1_funcs.c

Branch
------
REL_2_0_STABLE
