While playing with this patch under 8.1.2 at home I discovered a
mistake in how I manually applied one of the hunks to fe-auth.c.
Basically, the base code had changed and so the patch needed to be
modified slightly. This is because the code no longer either has a
freeable pointer under 'name' or has 'name' as NULL.
The attached patch correctly frees the string from pg_krb5_authname
(where it had been strdup'd) if and only if pg_krb5_authname returned
a string (as opposed to falling through and having name be set using
name = pw->name;). Also added a comment to this effect.
Please review.

I looked into this and it seems the problem is that the view doesn't
get flattened into the main query because of the has_nullable_targetlist
limitation in prepjointree.c. That's triggered because pg_roles has
'********'::text AS rolpassword
which isn't nullable, meaning it would produce wrong behavior if
referenced above the outer join.
Ultimately, the reason this is a problem is that the planner deals only
in simple Vars while processing joins; it doesn't want to think about
expressions. I'm starting to think that it may be time to fix this,
because I've run into several related restrictions lately, but it seems
like a nontrivial project.
In the meantime, reducing the LEFT JOIN to pg_roles to a JOIN as per
Peter's suggestion seems like the best short-term workaround.

Skip ambulkdelete scan if there's nothing to delete and the index is not

tuples when there's nothing to delete, and we can get a tuple count
from the heap as long as it's not a partial index. (hash actually can
skip anyway because it maintains a tuple count in the index metapage.)
GIST is not currently able to exploit this optimization because, due to
failure to index NULLs, GIST is always effectively partial. Possibly
we should fix that sometime.

I think that NUMERIC datatype has a problem in the performance that
the format on Tuple(Numeric) and the format to calculate(NumericVar)
are different. I understood that to reduce I/O. However, when many
comparisons or calculations of NUMERIC are executed, the conversion
of Numeric and NumericVar becomes a bottleneck.
It is profile result when "create index on NUMERIC column" is executed:

The create index command executes many comparisons of Numeric values.
Functions other than comparetup_index spent a lot of cycles for
conversion from Numeric to NumericVar.
An attached patch enables the comparison of Numeric values without
executing conversion to NumericVar. The execution time of that SQL
becomes half.

Improve the tests to see if ScalarArrayOpExpr is strict. Original coding

Improve my initial, rather hacky implementation of joins to append
relations: fix the executor so that we can have an Append plan on the
inside of a nestloop and still pass down outer index keys to index scans
within the Append, then generate such plans as if they were regular
inner indexscans. This avoids the need to evaluate the outer relation
multiple times.
