Also, add cross-reference from pg_shadow.passwd to pg_authid.rolpasswd and
fix a bit of markup I muffed in my previous commit.
Per discussion with Josh Kupershmidt.
It isn't, now that we ship the docs as loose files rather than a sub-tarball.
Also adjust the wording in a couple of places to make the lists of required
software read more consistently.
- remove excessive table cells
- moving function parameters into function tags rather than having
them being considered separate
- add return type column on XML2 contrib module functions list and
removing return types from function
- add table header to XML2 contrib parameter table

Backpatch to 9.0.X.
Since the code underlying pg_get_expr() is not secure against malformed
input, and can't practically be made so, we need to prevent miscreants
from feeding arbitrary data to it. We can do this securely by declaring
pg_get_expr() to take a new datatype "pg_node_tree" and declaring the
system catalog columns that hold nodeToString output to be of that type.
There is no way at SQL level to create a non-null value of type pg_node_tree.
Since the backend-internal operations that fill those catalog columns
operate below the SQL level, they are oblivious to the datatype relabeling
and don't need any changes.
which is perhaps not a terribly good spot for it but there doesn't seem to be
a better place. Also add a source-code comment pointing out a couple reasons
for having a separate lock file. Per suggestion from Greg Smith.
While at it, copy-edit the description of prefix-match marker support in
synonym dictionaries, and clarify the description of the default unaccent
dictionary a bit more.
Per gripe from Fujii Masao, though this is not exactly his proposed patch.
Categorize as DEVELOPER_OPTIONS and set context PGC_SIGHUP, as per Fujii,
but set the default to LOG because higher values aren't really sensible
(see the code for trace_recovery()). Fix the documentation to agree with
the code and to try to explain what the variable actually does. Get rid
of no-op calls trace_recovery(LOG), which accomplish nothing except to
demonstrate that this option confuses even its author.
This allows us to reliably remove all leftover temporary relation
files on cluster startup without reference to system catalogs or WAL;
therefore, we no longer include temporary relations in XLOG_XACT_COMMIT
and XLOG_XACT_ABORT WAL records.
Since these changes require including a backend ID in each
SharedInvalSmgrMsg, the size of the SharedInvalidationMessage.id
field has been reduced from two bytes to one, and the maximum number
of connections has been reduced from INT_MAX / 4 to 2^23-1. It would
be possible to remove these restrictions by increasing the size of
SharedInvalidationMessage by 4 bytes, but right now that doesn't seem
like a good trade-off.

functions to the core XML code. Per discussion, the former depends on
XMLOPTION while the others do not. These supersede a version previously
offered by contrib/xml2.
