woken by alarm we send SIGUSR1 to all backends requesting that they

I failed to 'cvs add' the new files and also neglected to bump catversion.

Attributes can now have options, just as relations and tablespaces do, and
the reloptions code is used to parse, validate, and store them.  For
simplicity and because these options are not performance critical, we store
them in a separate cache rather than the main relcache.

Also cleaned up some redundancies between the primary error messages and the

Applied patch by Boszormenyi Zoltan <zb@cybertec.at> to fix problem in auto-prepare mode if the connection is closed and re-opened and the previously prepared query is issued again.

PQescapeLiteral is similar to PQescapeStringConn, but it relieves the
caller of the need to know how large the output buffer should be, and
it provides the appropriate quoting (in addition to escaping special
characers within the string).  PQescapeIdentifier provides similar
functionality for escaping identifiers.

that would've been WAL-logged if archiving was enabled. If we encounter
such records in archive recovery anyway, we know that some data is
missing from the log. A WARNING is emitted in that case.

Original patch by Fujii Masao, with changes by me.

binary, revert PGDLLIMPORT decoration of global variables. I'm not sure
if there's any real harm from unnecessary PGDLLIMPORTs, but these are all
internal variables that external modules really shouldn't be messing
with. ThisTimeLineID still needs PGDLLIMPORT.

walreceiver as whole into a dynamically loaded module, split the
libpq-specific parts of it into dynamically loaded module and keep the rest
in the main backend binary.

Although Tom fixed the Windows compilation problems with the old walreceiver
module already, this is a cleaner division of labour and makes the code
more readable. There's also the prospect of adding new transport methods
as pluggable modules in the future, which this patch makes easier, though for
now the API between libpqwalreceiver and walreceiver process should be
considered private.

The libpq-specific module is now in src/backend/replication/libpqwalreceiver,
and the part linked with postgres binary is in
src/backend/replication/walreceiver.c.

Some more code and documentation cleanup along the way, as well as

Original patch from Tim Bunce, with a little editing from me.

Modify the "Escaping Strings for Inclusion in SQL Commands" section
to use a <variablelist> as the preceding and following sections do,
and merge the "Escaping Binary Strings for Inclusion in SQL Commands"
section into it.

This changes only the formatting of these sections, not the content.
It is intended to lay the groundwork for a follow-on patch to add
some new escaping functions, but it makes sense to commit this first,
for clarity.

dump IDs, because the array we're using is sized according to the highest
dump ID actually defined in the archive file.  In a partial dump there could
be references to higher dump IDs that weren't dumped.  Treat these the same
as references to in-range IDs that weren't dumped.  (The whole thing is a
bit scary because the missing objects might have been part of dependency
chains, which we won't know about.  Not much we can do though --- throwing
an error is probably overreaction.)

Also, reject parallel restore with pre-1.8 archive version (made by pre-8.0
pg_dump).  In these old versions the dependency entries are OIDs, not dump
IDs, and we don't have enough information to interpret them.

Per bug #5288 from Jon Erdman.
