pg_char_to_encoding() in multibyte disbaled case so that it does not
throw an error, rather return HARD CODED default value (currently SQL_ASCII).
This would solve the "non-mb backend vs. mb-enabled frontend" problem.

cleanup, ie, as soon as we have caught the longjmp.  This ensures that
current context will be a valid context throughout error cleanup.  Before
it was possible that current context was pointing at a context that would
get deleted during cleanup, leaving any subsequent pallocs in deep
trouble.  I was able to provoke an Assert failure when compiled with
asserts + -DCLOBBER_FREED_MEMORY, if I did something that would cause
an error to be reported by the backend large-object code, because indeed
that code operates in a context that gets deleted partway through xact
abort --- and CurrentMemoryContext was still pointing at it!  Boo hiss.

loops, but just arbitrarily failing at 1000 locks.

because StatFp never got set in that case.  Set it immediately before
use to eliminate such problems.

field value being displayed; produced coredump instead of the expected
<NULL> display.

thus causing failure if one sub-select had resjunk entries that the other
did not (cf. bug report from Espinosa 4/27/00).

cases where joinclauses were present but some joins have to be made
by cartesian-product join anyway.  An example is
SELECT * FROM a,b,c WHERE (a.f1 + b.f2 + c.f3) = 0;
Even though all the rels have joinclauses, we must join two of them
in cartesian style before we can use the join clause...

that might be hanging about.  Now it does ... amazing nobody noticed
this before ...

not cause any compatibility problems because stored rules don't contain
plan nodes --- in fact, we don't even have a readfunc for Unique nodes.

than BIND_DEFERRED.  That way, if the loaded library has unresolved
references, shl_load fails cleanly.  As we had it, shl_load would
succeed and then the dynlinker would call abort() when we try to call
into the loaded library.  abort()ing a backend is uncool.

that will actually work on the column datatype.
