Tom Lane	d4d48a5edd	Tweak new regression test case for better portability. Buildfarm says we get different plans on 32-bit and 64-bit platforms, probably because of MAXALIGN-related differences in memory-consumption calculations. Add some dummy WHERE clauses so that the planner estimates different sizes for the three generate_series() relations; that should stabilize the choice of join order.	12 years ago
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.

Robert Haas	bb818b53d4	Remove a couple of comments from the pg_lsn regression test. Previously, one of these was a negative test case, but that got changed along the way and the comments didn't get the memo. Michael Paquier	12 years ago
Robert Haas	7d03a83f4d	Add a pg_lsn data type, to represent an LSN. Robert Haas and Michael Paquier	12 years ago
