其他 Bug 修复和改进
本次更新还修复了过去几个月报告的 50 多个错误。其中一些问题仅影响版本 10，但更多的是影响所有受支持的版本。
Fix incorrect volatility and parallel-safety markings on several built-in functions to ensure correct query planning optimizations
Several fixes for partitioning, including potential crashes as well as allowing TRUE and FALSE to be used as partition bounds
Fix where a new TOAST value could be assigned to a dead-but-not-yet-vacuumed TOAST OID, which would result in an error similar to "unexpected chunk number 0 (expected 1) for toast value nnnnn"
Fix "CREATE TABLE ... LIKE" with bigint identity columns on 32-bit platforms
Fix memory leak within the runtime of a query that repeatedly executes hash joins
Several crash fixes around queries using GROUPING SET
Avoid failure if a query-cancel or session-termination interrupt occurs while committing a prepared transaction
Reduce locking during autovacuum worker scheduling, which prevents loss of potential worker concurrency
Fix possible slow execution of REFRESH MATERIALIZED VIEW CONCURRENTLY
Several fixes around query plans that use "index-only" scans
Avoid deadlocks in concurrent CREATE INDEX CONCURRENTLY commands that are run under SERIALIZABLE or REPEATABLE READ transaction isolation
Several fixes for SP-GiST indexes, including one collation-aware searches on text columns
Fixes related to counting the number of tuples in partial GiST, SP-GiST, and Bloom indexes
Several fixes for logical decoding and replication
Fix misquoting of values for list-valued GUC variables (e.g. local_preload_libraries, session_preload_libraries, shared_preload_libraries, temp_tablespaces) in dumps
Several fixes for pg_stat_activity
Several fixes for ecpg
Fix for pg_recvlogical to ensure compatibility with PostgreSQL versions released before 10
Several fixes for pg_rewind
