before comparison; if fields being joined are different widths then hashing
will yield wrong answer. Also, remove hashjoinable mark from all uses of
array_eq, because array structures may have padding bytes between elements
and the pad bytes are of uncertain content. This could be revisited if
array code is cleaned up.
Modify opr_sanity regress test to complain if array_eq operator is marked
hashjoinable.
1. Using 100 digits after decimal point on the default
make runtest.
2. Using 1000 digits after decimal point in a new target
make bigtest.
At the end of 'make runtest', a hint about the new bigtest is
printed.

in rules regression test, in order to eliminate bogus test 'failures'
that occur due to platform-dependent and join-implementation-dependent
ordering of tuples. I'm not sure that I got all of the SELECTs that need
ordering clauses --- we may need some more. But this takes care of the
diffs between my platform and Jan's.
hashjoin's hashFunc() so that it does the right thing with pass-by-value
data types (the old code would always return 0 for int2 or char values,
which would work but would slow things down a lot). Extend opr_sanity
regress test to catch more kinds of errors.
function is found in prosrc field of pg_proc, not proname. This allows
multiple aliases of a built-in to all be implemented as direct builtins,
without needing a level of indirection through an SQL function. Replace
existing SQL alias functions with builtin entries accordingly.
Save a few K by not storing string names of builtin functions in fmgr's
internal table (if you really want 'em, get 'em from pg_proc...).
Update opr_sanity with a few more cross-checks.
so remove them from MergeJoin node. Hack together a partial
solution for commuted mergejoin operators --- yesterday
a mergejoin int4 = int8 would crash if the planner decided to
commute it, today it works. The planner's representation of
mergejoins really needs a rewrite though.
Also, further testing of mergejoin ops in opr_sanity regress test.
rule system semantics by having Var nodes referenced across multiple
parsetrees when rules split them.
Added more tests to the rules regression test.
The code in question resulted from v6.3 based development and was
a little careless applied to the v6.5 source tree.
