Replace find_ok assert with elog panic message.
Improve the elog panic message introduced in previous commit. Fix ForeignScan estimation logic.
Switch from AQO_EXPLAIN define to the two user GUCS: aqo.details and aqo.show_hash. New ExplainOneNode hook allows to add info into explain of each node.
AQO supports push-down of trivial JOIN and JOIN with mergejoinable clauses.
short-living planner memory context. Some indentations fixed.
Big commit. To avoiding UPDATE/UPDATE/DELETE/INSERT conflicts we use user locks on a pair (query_hash, fspace_hash) to guarantee that only one backend can do INSERT/UPDATE/DELETE of a aqo table row. Also we use dirty snapshot to see concurrently inserted/updated tuples. Such conflict may cause deadlocks on end-of-transaction waiting. Currently, if we detected such conflict, we refuse from we ML-base changing.
collection. Add some comments on auto tuning algorithm. change the intelligent.sql test to avoid unsteady behaviour in the intelligent mode. Change the logic of a node hash showing. Add regression test on forced stat collection mode.
Enable ICU and TAP tests in the AQO CI
Add regression test on currently unsupported planner clauses.

test for successful passing. Check on passing of this rule is added into CI/CD script. Further we need to implement execution of the regression tests in different modes of AQO repeatedly on the same instance and the same database.
parallel operation, as either the master or a worker.
Now AQO could clean global data, such of query_text at the end of transaction. It is needed because errors during query execution phases. We need to be sure that all such data cleaned before the next query execution. Interface of the add_query_text routine changed.
the query must be read-only (by the flag XactReadOnly).
Add ignore option in pg_regress schedule for non-passed tests.
It is needed to exclude problems with recursive execution induced by cache invalidation.
established by previous execution of this plan in another query.
