Tom Lane	4c8ab1b91d	Add btree and hash opclasses for pg_lsn. This is needed to allow ORDER BY, DISTINCT, etc to work as expected for pg_lsn values. We had previously decided to put this off for 9.5, but in view of commit `eeca4cd35e` there's no reason to avoid a catversion bump for 9.4beta2, and this does make a pretty significant usability difference for pg_lsn.

Bruce Momjian	0a78320057	pgindent run for 9.4 This includes removing tabs after periods in C comments, which was applied to back branches, so this change should not effect backpatching.	12 years ago
Robert Haas	694e3d139a	Further code review for pg_lsn data type. Change input function error messages to be more consistent with what is done elsewhere. Remove a bunch of redundant type casts, so that the compiler will warn us if we screw up. Don't pass LSNs by value on platforms where a Datum is only 32 bytes, per buildfarm. Move macros for packing and unpacking LSNs to pg_lsn.h so that we can include access/xlogdefs.h, to avoid an unsatisfied dependency on XLogRecPtr.	12 years ago
Robert Haas	844a28a9dd	pg_lsn macro naming and type behavior revisions. Change pg_lsn_mi so that it can return negative values when subtracting LSNs, and clean up some perhaps ill-considered macro names.	12 years ago
