When compiling a plpgsql trigger function, include the OID of the table
the trigger is attached to in the hashkey. This ensures that we will
create separate compiled trees for each table the trigger is used with,
avoiding possible datatype-mismatch problems if the tables have different
rowtypes. This is essentially the same bug recently identified in plpython
--- though plpgsql doesn't seem as prone to crash when the rowtype changes
underneath it. But failing robustly is no substitute for just working.

Update documentation to reflect the fact that ORDER BY, GROUP BY, etc

particular operator names have the needed semantics.

Create a 'type cache' that keeps track of the data needed for any particular
datatype by array_eq and array_cmp; use this to solve problems with memory
leaks in array indexing support. The parser's equality_oper and ordering_oper
routines also use the cache. Change the operator search algorithms to look
for appropriate btree or hash index opclasses, instead of assuming operators
named '<' or '=' have the right semantics. (ORDER BY ASC/DESC now also look
at opclasses, instead of assuming '<' and '>' are the right things.) Add
several more index opclasses so that there is no regression in functionality
for base datatypes. initdb forced due to catalog additions.

(I always forget what the magic numbers 0 through 2 means for the
"syslog" option.)
By the way: The "virtual_host" parameter is a bad name for that
particular option, I think. "Virtual host" signals that PostgreSQL will
behave differently according to which IP address it's contacted (like
Apache's virtual host support which makes the web-server serve different
sites according to different criteria). A better word for the options
would be "tcpip_listen_addr" or something like that.

Rewrite array_cmp to not depend on deconstruct_array. Should be a little

libpq failed to cope with COPY FROM STDIN if the command was issued
via extended query protocol, because it sends Sync right after Execute
without realizing that the command to be executed is COPY. There seems
to be no reasonable way for it to realize that, either, so the best fix
seems to be to make the backend ignore Sync during copy-in mode. Bit of
a wart on the protocol, but little alternative. Also, libpq must send
another Sync after terminating the COPY, if the command was issued via
Execute.

Repair potential deadlock created by recent changes to recycle btree
index pages: when _bt_getbuf asks the FSM for a free index page, it is
possible (and, in some cases, even moderately likely) that the answer
will be the same page that _bt_split is trying to split. _bt_getbuf
already knew that the returned page might not be free, but it wasn't
prepared for the possibility that even trying to lock the page could
be problematic. Fix by doing a conditional rather than unconditional
grab of the page lock.
