Add description of *ScanRegExp hints in the document.

Mark hint table as a configuration table.

The table hint_plan.hints is a configuration table of
pg_hint_plan. Mark it as such, as well as its sequence table.

Back patch to pg_hint_plan96.

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.

Follow the core chnges.

Update core.c following the changes in the core. It makes difference
in the regression test result so update it, too.

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.

Give correct query location to generate_normalized_query.

There was a thinko about query_loc of generate_normalized_query which
causes a crash. For example a query is following a sequence of
semicolons (by \; in psql input) longer than the length after the last
placeholder to the end of the query, the function causes assertion
failure. Anyway prepared statements lose that value so we just pass 0
as the query_loc for consistent behavior.

Fix crash bug caused by plancache invalidation

Issue: 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

Fix behavior of nested planning

Issue: https://github.com/ossc-db/pg_hint_plan/issues/39

When planning is nested by function call, the hints in the function
should affect the corresponding query. Maybe 9599067 introduced
that. Fix the nested planning behavior.

Fix a typo.

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

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.

Fix definition of is_dummy_rel based on changes to community PostgreSQL 11.3

This breaks compatibility with older minor versions, but don't bother
keeping it. Binary built using newer PG minor versions works for older
minor versions.

Use ParallelHint in ParallelHintCreate()

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.

9599067 2019-02-26 18:30:07 Kyotaro Horiguchi

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.
