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.

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.

098f919 2019-01-17 18:47:49 Kyotaro Horiguchi

Fix content of llvmjit package

The previous release is missing index.bc file and mislocating .bc file
in the llvmjit subpackage. The former is created at make install time
so use the standard make file to rpm-build.

Call standrad_ProcessUtility when no hook is set

The last commit 2bbb376 forgot the case of no previous hook function
in the ProcessUtility hook function. Fix it.

2bbb376 2019-01-07 19:08:18 Kyotaro Horiguchi

Support prepared statements on extended protocol

However pg_hint_plan doesn't fully consider the extended protocol,
commit c05bb31 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

6769ce8 2019-01-07 19:08:18 Kyotaro Horiguchi

Remove an useless variable

commit c05bb31 made the variable stmt_name useless. Remove it.

6f23970 2018-12-05 17:31:40 Kyotaro Horiguchi

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.

d1879e0 2018-12-05 17:31:35 Kyotaro Horiguchi

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

d5d6719 2018-11-13 18:02:35 Kyotaro Horiguchi

a subpackage llvmjit, which installs a bitcode file needed for JIT

e220378 2018-11-13 16:00:34 Kyotaro Horiguchi

Fix regression test following core's behavior

Some changes has been made on GUC default value and behavior. Follow

Change version to 1.3.2.

f222c03 2018-11-13 15:55:02 Kyotaro Horiguchi

Fix debug output level control

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.

18fd79f 2018-11-13 15:55:02 Kyotaro Horiguchi

Fix bogus error handling

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

0a3456e 2018-11-13 15:54:20 Kyotaro Horiguchi

Change version to 1.3.1.

1.3.0 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.

Took in several improvements of pg_stat_statements

Following two commits are took in.

83f2061dd0 Teach contrib/pg_stat_statements to handle multi-statement commands better.
0bb51aa967 Improve parsetree representation of special functions such as CURRENT_DATE.

The following one makes change of documented behavior of pg_hint_plan
so it is not took in.

a6f22e8356 Show ignored constants as "$N" rather than "?" in pg_stat_statements.

5f581e4 2018-06-14 19:15:14 Kyotaro Horiguchi

Support PG11

Support PG11. Just adapted to PG11 in this version. No behavior
changes except Parallel hint. PG11 gets many new parallel features and
as a matter of course they made deadly impact on Parallel hint. It no
longer works in the same way with the earlier version except for quite
simple cases.
