Adjust regression test

Core behavior has changed, 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;

Adjust regression test

Some regression test items need adjustment due to change of server
behavior. The way the regression test ignores unstable portions of
EXPLAIN output is changed along with that.

Minor document fix

Just fix versions of PostgreSQL and OS.

Changed version to 1.3.2

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.

Remove unnecessary file

Commit c7888a1 added wrong file. Remove it.

Fix regression test following core's behavior

Some changes has been made on GUC default value and behavior. Follow
the change. No change was made on pg_hint_plan's behavior.

Changed version to 1.1.7

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

Fix debug output level control

Fix bogus error handling

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

Change target version to PG11 and fix the SPEC file

Change targetr version to PG11. SPEC file was changed so that genearte
a subpackage llvmjit, which installs a bitcode file needed for JIT
compilation.

Fix copyright year

Fix regression test following core's behavior
