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.

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.
