Also do some further work in the back branches, where quite a bit wasn't
covered by Magnus' original back-patch.

There was an incorrect Assert in hstoreValidOldFormat(), which would cause
immediate core dumps when attempting to work with pre-9.0 hstore data,
but of course only in an assert-enabled build.

Also, ghstore_decompress() incorrectly applied DatumGetHStoreP() to a datum
that wasn't actually an hstore, but rather a ghstore (ie, a gist signature
bitstring).  That used to be harmless, but could now result in misbehavior
if the hstore format conversion code happened to trigger.  In reality,
since ghstore is not marked toastable (and doesn't need to be), this
function is useless anyway; we can lobotomize it down to returning the
passed-in pointer.

Both bugs found by Andrew Gierth, though this isn't exactly his proposed
patch.

There is much else to do here, but this patch seems useful in its own right
for as long as this code survives.

- Rename TSParserGetPrsid to get_ts_parser_oid.
- Rename TSDictionaryGetDictid to get_ts_dict_oid.
- Rename TSTemplateGetTmplid to get_ts_template_oid.
- Rename TSConfigGetCfgid to get_ts_config_oid.
- Rename FindConversionByName to get_conversion_oid.
- Rename GetConstraintName to get_constraint_oid.
- Add new functions get_opclass_oid, get_opfamily_oid, get_rewrite_oid,
  get_rewrite_oid_without_relid, get_trigger_oid, and get_cast_oid.

The name of each function matches the corresponding catalog.

Operating directly on the underlying varlena saves palloc and memcpy
overhead, which testing shows to be significant.

supposing that they should set SHLIB_LINK rather than LDFLAGS_SL.  Since these
don't go through Makefile.shlib that was a no-op on most platforms.  Also
regularize the few platform-specific Makefiles that did pay attention to
SHLIB_LINK: it seems that the real value of that is to pull in BE_DLLLIBS,
so do that instead.  Per buildfarm failures on cygwin.

Also set user name for pg_dumpall in pg_upgrade.

This is an oversight in my previous patch to deprecate => as an operator
name.  Per buildfarm.

This is not yet in any released version, so we still have the option to
change the name.  We may want to reserve the token => in a future release.
