Restore current hint state when returned from non-hinted query planning.

If no hint is given for the current level query, pg_hint_plan_planner
calls the next level of planner after erasing the
current_hint_state. But it forgot to restore the state before the
planning of the rest part of the current-level query. It is
(a-kind-of) broken by the commit d422966 but overlooked as an
inevitable side-effect of the fix. Get back the behavior by restoring
current_hint_state after returned from the lower level planner with
unhinted query.

Use proper type for non-integer GUC options.

pg_hint_plan internally preserved numeric options into integer
variable regardless of their types, which leads to unintentional
change of the values. Handle double values in the proper way.

Fix Rows hint parsing

This is a long standing bug that Rows hint with no parameter causees a
crash. Fixed the Rows hint parser.

Fix crash bug caused by plancache invalidation

https://github.com/ossc-db/pg_hint_plan/issues/41

After plancache is invalidated then revaliated, get_query_string
accesses query_list of invalid plansource then crash. Ignore invalid
plancache and get the correct hint string and Query node at the next
planning time during revalidation.

On the way fixing this, a bug related to planner reentrance is
fixed. That fix causes behavioral change for nested
planning. Previously outer-level hint (wrongly) overrides inner-level
query but currenlty outer-level hint no longer affects inner-level
query.

Use tuple-only mode to stablize EXPLAIN output containing @abs_srcdir@.

The line containing @abs_srcdir@ can be longer than the header line
and if it is, the test will fail. Use tuple-only mode to get rid of
the unstable part from the EXPLAIN output.

Fix compiling error on Solaris

The 'LDFLAGS+=-Wl,--build-id' option is for rpm building in Linux like
OS. The SunOS is not native support the option
'LDFLAGS+=-Wl,--build-id' . So, we disable this option in SunOS while
compiling.

Committed a bit tweaked version from the orignal.

Stabilize regression test.

Further unstability is found about stats reset. Inserted more 1 second
sleeps to stabilize it.

Do null-check of error_context_stack before use

The variable is accessed without null checking when planner is called
in the context of pl/pgsql. Fix it. Back-patched up to pg_hint_plan94.

Silence some compilers

Some compilers seem to complain about the previous patch, that
prev_hint_str is used uninitialized. Actually it is not but move the
initialization code out of the PG_TRY() section so that such compilers
would be quiet.

Correctly handle planner nesting

pg_hint_plan assumed that plpgsql is the only source of nested planner
calls. Actually nested call can be made in any shapes. Most of the
cases doesn't harm but in a special case where pg_dbms_stats makes a
SPI call during query planning, that affects subsequent planner
work. Hints lose effect when pg_dbms_stats searches "locked
statistics" tables while planning the target query.

Fix reverse link of hint_list.html

pg_hint_plan.html and hint_list.html pointed to the Japanese version
of main document. Fixed it.

Fix documentation.

Fixed wrong or stale descriptions, and poor or broken styles.

Use make install to build in prmbuild directory instaed of using
install command to individual file to reduce maintenance labor.

Call standrad_ProcessUtility when no hook is set

The last commit dff1e4a forgot the case of no previous hook function
in the ProcessUtility hook function. Fix it.

Support prepared statements on extended protocol

However pg_hint_plan doesn't fully consider the extended protocol,
commit 89149ce accidentially broke the case where an analyzed prepared
statement is executed on extended protocol. This patch fixes that only
for the hints-in-comment case. Hint-table still doesn't work in the
case since query-normalization needs Query, which is not available in
planner_hook.

Remove an useless variable

commit 89149ce made the variable stmt_name useless. Remove it.

Planning behavior has been changed in core. Adjust regression test.

Fix for union-on-inheritance case

setup_hint_enforcement may pick up a wrong hint when multiple
subqueries access inheritance tables. This leads to failure to apply
hints on other than the first subquery.

Don't reset plpgsql nest level at every command end

Clean up code for global exit is forgetting about loops that run
hinted commands multiple times. This leads to pg_hint_plan's failure
to affect after the first execution of the inner commands.
The hint below worked only for the first time.

FOR outer IN EXECUTE 'outer-command' LOOP
FOR inner IN EXECUTE '/*+ hint */ inner-command' LOOP
<something>
END LOOP;
END LOOP;

Changed version to 1.2.4

Previously parse_messages and message_level were binded to the same
internal variable. Separate the two GUCs. On the way doing this some
mssages that did not honor the variable were fixed. Default behavior
is not changed but the the two variables works differently from the
previous version, perhaps closer to expected.

Fix debug output level control

Previously parse_messages and message_level were binded to the same

Fix bogus error handling

For somewhat reason set_config_int32_options does bogus error
handling. Howerver that error cannot be happen, fixed it.

Change version to 1.2.3.

1.2.2 has a crash bug in Describe message of extended protocol
path. If server receives the message after invalidation of
corresponding query cache, pg_hint_plan crashes.

core.
