There have been many bug fixes for PostgreSQL 11 reported during the Beta 1 period and applied to the Beta 2 release. Several bug fixes reported for version 10 or earlier that also affected version 11 are included in the Beta 2 release. These fixes include:
-* Several fixes for XML support, including using the document node as the context for XPath queries as defined in the SQL standard, which affects the `xpath` and `xpath_exists` functions
+* Several fixes for XML support, including using the document node as the context for XPath queries as defined in the SQL standard, which affects the `xpath` and `xpath_exists` functions, as well as XMLTABLE
* Several fixes related to VACUUM, including potential data corruption issues
* Fixes for partitioning, including ensuring partitioning works with temporary tables, eliminating a needless additional partition constraint checks on `INSERT`s and generating incorrect paths for partitionwise aggregates
* Fix for potential replica server crashes where a replica would attempt to read a recycled WAL segment
* Fixes for `pg_replication_slot_advance` including returning `NULL` if slot is not advanced and changes for how the slot is updated depending on if it is a physical or logical replication slot
* Ensure `pg_resetwal` works with relative paths to data directory
* Fixes for query parallelism, including preventing a crash by ignoring "parallel append" for parallel unsafe paths in a query plan
-* Fix returning accurate results with "variance" and similar aggregate functions when executed using parallel query
+* Fix returning accurate results with `variance` and similar aggregate functions when executed using parallel query
* Fix issue where `COPY FROM .. WITH HEADER` would drop a line after every 4,294,967,296 lines processed
* Ensure the "B" (bytes) parameter is accepted by all memory-related configuration parameters

for XPath queries as defined in the SQL standard, which affects the `xpath` and
