Bug fixes
-
Consider tuple duplicity in maintenance of EXISTS views by @yugo-n in #83
Previously, the duplicity of row was not considered and only one tuple was inserted even when duplicated tuples are generated as a result of inserting a tuple into a table in an EXISTS subquery.
-
Fix checking for expressions containing an EXISTS subquery by @thoshiai in #71
EXISTS subquery is currently allowed only directly under WHERE clause or in AND expression that is directly under WHERE. However, the check was insufficient previously so that views using expressions other than AND containing an EXISTS subquery could be created without an error and it caused incorrect maintenance results.
-
Check if PgIvmImmvRelationId is invalid before open it by @bytezzz in #78
Fix an error that occurs at dropping tables that occurs when pg_ivm is installed by shared_preload_libraries without executing CREATE EXTENSION command.
-
Fix an error raised when dropping pg_ivm extension by @yugo-n in d67995c
Previously, DROP EXTENSION pg_ivm failed due to the failure of opening the index on the pg_ivm_immv catalog table, because the index had been already dropped at that time.
