versions of gcc (I'm seeing it with Apple's gcc 4.0.1). I think the
reason we did not see this before was that the assert() macros in the
regex code were all no-ops till recently.
are really redundant, since we invented a regdictionary alias type.
We can have just one function, declared as taking regdictionary, and
it will handle both behaviors. Noted while working on documentation.
Also enable translation of PG_WIN874, which certainly seems to have an
obvious translation now, though maybe it did not at the time this table's
ancestor was created.
Notably, standardize on using "token" for the strings output by a parser,
while "lexeme" is reserved for the normalized strings produced by a
dictionary.
when relkind = RELKIND_RELATION. This syncs these tests with the Asserts
in tuptoaster.c, and ensures that we won't ever try to, for example,
compress a sequence's tuple. Problem found by Greg Stark while stress-testing
with much-smaller-than-normal page sizes.
coding this was seen as useless, but the problem with not including them
is that the error message will often be something about authentication
failure, rather than the more helpful one about 'role is not permitted
to log in'. Per discussion.
renumbering of encoding IDs done between 8.2 and 8.3 turns out to break 8.2
initdb and psql if they are run with an 8.3beta1 libpq.so. For the moment
we can rearrange the order of enum pg_enc to keep the same number for
everything except PG_JOHAB, which isn't a problem since there are no direct
references to it in the 8.2 programs anyway. (This does force initdb
unfortunately.)
Going forward, we want to fix things so that encoding IDs can be changed
without an ABI break, and this commit includes the changes needed to allow
libpq's encoding IDs to be treated as fully independent of the backend's.
The main issue is that libpq clients should not include pg_wchar.h or
otherwise assume they know the specific values of libpq's encoding IDs,
since they might encounter version skew between pg_wchar.h and the libpq.so
they are using. To fix, have libpq officially export functions needed for
encoding name<=>ID conversion and validity checking; it was doing this
anyway unofficially.
It's still the case that we can't renumber backend encoding IDs until the
next bump in libpq's major version number, since doing so will break the
8.2-era client programs. However the code is now prepared to avoid this
type of problem in future.
Note that initdb is no longer a libpq client: we just pull in the two
source files we need directly. The patch also fixes a few places that
were being sloppy about checking for an unrecognized encoding name.
it affects. The original coding neglected tablespace entirely (causing
the indexes to move to the database's default tablespace) and for an index
belonging to a UNIQUE or PRIMARY KEY constraint, it would actually try to
assign the parent table's reloptions to the index :-(. Per bug #3672 and
subsequent investigation.
8.0 and 8.1 did not have reloptions, but the tablespace bug is present.
