First cut at doing LIKE/regex indexing optimization in
optimizer rather than parser. This has many advantages, such as not
getting fooled by chance uses of operator names ~ and ~~ (the operators
are identified by OID now), and not creating useless comparison operations
in contexts where the comparisons will not actually be used as indexquals.
The new code also recognizes exact-match LIKE and regex patterns, and
produces an = indexqual instead of >= and <=.
This change does NOT fix the problem with non-ASCII locales: the code
still doesn't know how to generate an upper bound indexqual for non-ASCII
collation order. But it's no worse than before, just the same deficiency
in a different place...
Also, dike out loc_restrictinfo fields in Plan nodes. These were doing
nothing useful in the absence of 'expensive functions' optimization,
and they took a considerable amount of processing to fill in.

Remove 'restrictinfojoinid' field from RestrictInfo nodes.
The only place it was being used was as temporary storage in indxpath.c,

carry the info for two different joins. Right fix is to return a second

identified by Hiroshi (incorrect cost attributed to OR clauses

was trying to allow selectivities of OR subclauses to be passed in
from outside, but noplace was actually passing any useful data, and
set_rest_selec() was passing wrong data.
Restructure representation of "indexqual" in IndexPath nodes so that
it is the same as for indxqual in completed IndexScan nodes: namely,
a toplevel list with an entry for each pass of the index scan, having
sublists that are implicitly-ANDed index qual conditions for that pass.
You don't want to know what the old representation was :-(

While I was running some tests in psql, trying to figure out how to change
the query string to handle any length, I discovered that under certain
conditions, psql will core dump when handling long strings. Thus, the
patch. It was caused by a buffer overrun, probably not noticeable in a lot
of cases, but pretty noticeable in mine.
Problem was caused by the fact that the length check is only performed after
the check for a ; to get the end of the query and execute.
