maybe just change the tsrange type to daterange, then the dot out file
will be far less verbose.

minor issues while reviewing v27, 0001 to 0004.
transformFkeyGetPrimaryKey comments need to update,
since bool pk_period also returned.

+/*

+  ListCell **old_pfeqop_item,
+  Oid pktype, Oid fktype, Oid opclass,
+  Oid *pfeqopOut, Oid *ppeqopOut, Oid *ffeqopOut)

I think the above comments is
`Sets the operators for pfeqopOut, ppeqopOut, and ffeqopOut.`.

can be
if (is_temporal && !fkconstraint->fk_with_period)
ereport(ERROR,
(errcode(ERRCODE_INVALID_FOREIGN_KEY),
errmsg("foreign key uses PERIOD on the referenced table but not the
referencing table")));

refactor decompile_column_index_array seems unnecessary.
Peter already mentioned it at [1], I have tried to fix it at [2].

I  don't understand the "expression elements" in the comments, most of
the tests case is like
`
PRIMARY KEY (id, valid_at WITHOUT OVERLAPS)
`
+ *pk_period = (indexStruct->indisexclusion);
can be
`+ *pk_period = indexStruct->indisexclusion;`
