functionality, while creating an ambiguity in usage with ORDER BY that at
least two people have already gotten seriously confused by. Also, add an
opr_sanity test to check that we don't in future violate the newly minted
policy of not having built-in aggregates with the same name and different
numbers of parameters. Per discussion of a complaint from Thom Brown.
the parameters of \connect, and fix oversight of not enabling translation
of the messages. Also, adjust \connect's similar messages to match, and
deal with 8.2-era violation of basic translatability guidelines there.
Block elements with verbatim formatting (literallayout, programlisting,
screen, synopsis) should be aligned at column 0 independent of the surrounding
SGML, because whitespace is significant, and indenting them creates erratic
whitespace in the output. The CSS stylesheets already take care of indenting
the output.
Assorted markup improvements to go along with it.
table with a <variablelist> carrying the same information. Previously the
9.0 documentation was failing to build as a US-size PDF file. It's quite
obscure what the real problem is or why this avoids it, but we need a hack
now so we can build docs for beta4.
In passing do a bit of editing in the AIX installation docs, in particular
remove a long-obsolete claim that the regression tests are likely to fail.
Avoid hard-coding lockmode used for many altering DDL commands, allowing easier
future changes of lock levels. Implementation of initial analysis on DDL
sub-commands, so that many lock levels are now at ShareUpdateExclusiveLock or
ShareRowExclusiveLock, allowing certain DDL not to block reads/writes.
First of number of planned changes in this area; additional docs required
when full project complete.
I've added a quote_all_identifiers GUC which affects the behavior
of the backend, and a --quote-all-identifiers argument to pg_dump
and pg_dumpall which sets the GUC and also affects the quoting done
internally by those applications.
Design by Tom Lane; review by Alex Hunsaker; in response to bug #5488
filed by Hartmut Goebel.
Normally, we automatically restart after a backend crash, but in some
cases when PostgreSQL is invoked by clusterware it may be desirable to
suppress this behavior, so we provide an option which does this.
Since no existing GUC group quite fits, create a new group called
"error handling options" for this and the previously undocumented GUC
exit_on_error, which is now documented.

This adds a libpq connection parameter requirepeer that specifies the user
name that the server process is expected to run under.

parameter against server cert's CN field) to succeed in the case where
both host and hostaddr are specified. As with the existing precedents
for Kerberos, GSSAPI, SSPI, it is the calling application's responsibility
that host and hostaddr match up --- we just use the host name as given.
Per bug #5559 from Christopher Head.
In passing, make the error handling and messages for the no-host-name-given
failure more consistent among these four cases, and correct a lie in the
documentation: we don't attempt to reverse-lookup host from hostaddr
if host is missing.
Back-patch to 8.4 where SSL cert verification was introduced.
rather than just $N. This brings the display of nestloop-inner-indexscan
plans back to where it's been, and incidentally improves the display of
SubPlan parameters as well. In passing, simplify the EXPLAIN code by
having it deal primarily in the PlanState tree rather than separately
searching Plan and PlanState trees. This is noticeably cleaner for
subplans, and about a wash elsewhere.
One small difference from previous behavior is that EXPLAIN will no longer
qualify local variable references in inner-indexscan plan nodes, since it
no longer sees such nodes as possibly referencing multiple tables. Vars
referenced through PARAM_EXEC Params are still forcibly qualified, though,
so I don't think the display is any more confusing than before. Adjust a
couple of examples in the documentation to match this behavior.
