- Added support for PG operators in cypher. Some hardcoded operators were removed, since they are now covered by the general operator handling.
- Added full typecast syntax that allows for type modifiers.
- These changes also improve interoperability with other extensions, as reflected in the regression tests.
- Fixed some operator signatures in .sql

(https://lists.apache.org/thread/qh4h2z6hsjy2v7wg8mwfnl6cbjp28y08) - Decrease required PR approvals by one. (https://lists.apache.org/thread/kmz155t6k0h3b26fjpz36924zthqjlpm) - Fixed a warning reported by apache infra i.e. "An error occurred while processing the github feature in .asf.yaml: GitHub discussions can only be enabled if a mailing list target exists for it." * Update labeler.yml Adjust workflow/labeler.yml to add permissions. * Adjust CI for PG17 after rename from PG17_prepare (#2182) Adjusted the following CI files (workflows) for PG17, they originally pointed to PG17_prepare - modified: .github/workflows/go-driver.yml modified: .github/workflows/installcheck.yaml modified: .github/workflows/jdbc-driver.yaml modified: .github/workflows/nodejs-driver.yaml modified: .github/workflows/python-driver.yaml modified: drivers/docker-compose.yml modified: .github/labeler.yml * Reimplement list comprehension (#2169) (#2188) * Revert "Fix issue 1955 - List comprehension in WHERE clause (#2094)" This reverts commit 0f0d9be. * Revert "Fix error using list comprehension with WITH * (#1838)" This reverts commit 5e08a2f. * Revert "Fix shift/reduce conflict in grammar (#1719)" This reverts commit fab3119. * Revert "Implement list comprehension (#1610)" This reverts commit 3b2b394. * Reimplement list comprehension - Reimplement list comprehension to use ARRAY sublinks. - Some test results were not correct. All the test results that are modified are correct and are verified with neo4j. - Also resolves the issue of using list comprehension in MERGE clause (1611) and issue 1850 * Add expression tree walkers for cypher nodes - Added cypher_raw_expr_tree_walker and cypher_expr_tree_walker, based on Postgres's raw_expression_tree_walker and expression_tree_walker. These follow the same walker API as Postgres and add support for Cypher-specific nodes. - Also added the agtype[] to agtype func and typecast to 1.5.0-y.y.y.sql - Simplifies logic for cypher_subquery handling in where clause. - Fixes a crash when list comprehension in the WHERE clause references a variable from the preceding MATCH clause. * Add support for operators in cypher query (#2172) - Fixed some operator signatures in .sql - Added support for PG operators in cypher. Some hardcoded operators are removed, since they are now covered by the general operator handling. - Added full typecast syntax that allows for type modifiers. - These changes also improve interoperability with other extensions, as reflected in the regression tests. - Added a new function to check if graph_oid exists. * Prevent object access hook from accesing not installed namespace (#2161) Currently we cannot install Age to shared_preload_libraries if pg_cron is installed.
