This reverts portions of commit6dcfac9696, which is wrong in trying to use a *GetDatum() that matches with the C types of the values read. *GetDatum() should match with the output argument types of the SQL functions. The portions of6dcfac9696that are right regarding this rule are: - gistget.c, where the GiST support functions use DatumGetUInt16() to retrieve the strategy number. - The BRIN code for strategynum, used in syscache lookups. The adjustments done in this commit are for pageinspect, pg_buffercache and pg_lock_status(). While double-checking the whole state of the tree regarding non-matching pairs of DatumGet*() and *GetDatum(), I have found much more code paths that are incorrect, unrelated to6dcfac9696. These may be adjusted in the future, in a different patch (perhaps not for v19, as we are already past feature freeze).
