We've now seen more than one gripe from somebody who didn't get the memo
about how to install contrib modules in 9.1. Try to make it a little more
prominent that you aren't supposed to call the scripts directly anymore.
This example wasn't updated when we changed the behavior of bpcharlen()
in 8.0, nor when we changed the number of parameters taken by the bpchar()
cast function in 7.3. Per report from lsliang.
The previous coding resulted in contrib modules unintentionally overriding
the use of CONTRIB_TESTDB. There seems no particularly good reason to
allow that (after all, the makefile can set CONTRIB_TESTDB if that's really
what it intends).
In passing, document REGRESS_OPTS where the other pgxs.mk options are
documented.
Back-patch to 9.1 --- in prior versions, there were no cases of contrib
modules setting REGRESS_OPTS without including the --dbname switch, so
while the coding was fragile there was no actual bug.
There is what may actually be a mistake in our markup. The problem is
in a situation like
<para>
<command>FOO</command> is ...
there is strictly speaking a line break before "FOO". In the HTML
output, this does not appear to be a problem, but in the man page
output, this shows up, so you get double blank lines at odd places.
So far, we have attempted to work around this with an XSL hack, but
that causes other problems, such as creating run-ins in places like
<acronym>SQL</acronym> <command>COPY</command>
So fix the problem properly by removing the extra whitespace. I only
fixed the problems that affect the man page output, not all the
places.
Somebody added a cross-reference to shared_preload_libraries, but wrote the
wrong variable name when they did it (and didn't bother to make it a link
either).
Spotted by Christoph Anton Mitterer.
Also change "switch" to "arg" because "switch" is a bit of a sloppy
term. So the environment variable is called
PSQL_EDITOR_LINENUMBER_ARG. Set "+" as hardcoded default value on
Unix (since "vi" is the hardcoded default editor), so many users won't
have to configure this at all. Move the documentation around a bit to
centralize the editor configuration under environment variables,
rather than repeating bits of it under every backslash command that
invokes an editor.
This function supports untranslated detail messages, in the same way that
errmsg_internal supports untranslated primary messages. We've needed this
for some time IMO, but discussion of some cases in the SSI code provided
the impetus to actually add it.
Kevin Grittner, with minor adjustments by me
In the example for decode(), show the bytea result in hex format,
since that's now the default. Use an E'' string in the example for
quote_literal(), so that it works regardless of the
standard_conforming_strings setting. On the functions-for-binary-strings
page, leave the examples as-is for readability, but add a note pointing out
that they are shown in escape format. Per comments from Thom Brown.
Also, improve the description for encode() and decode() a tad.
Backpatch to 9.0, where bytea_output was introduced.
