Changelog

Table functions no longer require any permissions to be used. (Enterprise only.)

Fixed an issue in binary encoding and decoding of array types in PostgreSQL wire protocol affecting the npgsql driver.
As Microsoft Windows does not support sending signals, stop attempting to handle the USR2 signal on Windows platforms as it pollutes the log with an unnecessary stacktrace.
Fixed a performance regression which occurred in queries where a literal was compared against an array column of a different type. For example: SELECT * FROM t1 WHERE 1 = ANY(int_arr_column) The array column would have been converted to long although the literal on the left could have been converted to integer.
Fixed an issue where the order of the relations in a FROM clause would expose fields between the relations. An error was thrown during execution of the statements.
Fixed incorrect HTTP responses on the BLOB API of subsequent requests after an error response occurred, e.g., 404 Not Found.
Fixed an issue that caused ANY to not work correctly on nested arrays.
Fixed an issue that would cause a NullPointerException to be thrown when executing an EXPLAIN statement for a CROSS JOIN.
