pgsql: Be more consistent about masking xl_info with ~XLR_INFO_MASK. - Mailing list pgsql-committers

Be more consistent about masking xl_info with ~XLR_INFO_MASK.

Generally, WAL resource managers are only supposed to examine the
top 4 bits of a WAL record's xl_info; the rest are reserved for
the WAL mechanism itself.  A few places were not consistent about
doing this with respect to XLOG_CHECKPOINT and XLOG_SWITCH records.
There's no bug currently, since no additional bits ever get set in
these specific record types, but that might not be true forever.
Let's follow the generic coding rule here too.
