Īvoid alias conflicts in queries generated for REFRESH MATERIALIZED VIEW CONCURRENTLY (Tom Lane, Bharath Rupireddy).The previous coding allowed ALTER EXTENSION ADD/DROP to occur concurrently with DROP EXTENSION, leading to a crash or corrupt catalog entries. Make ALTER EXTENSION lock the extension when adding or removing a member object (Tom Lane) Make pg_filenode_relation(0, 0) return NULL rather than failing (Justin Pryzby) įix pg_size_pretty(bigint) to round negative values consistently with the way it rounds positive ones (and consistently with the numeric version) (Dean Rasheed, David Rowley).įix division-by-zero failure in to_char() with EEEE format and a numeric input value less than 10^(-1001) (Dean Rasheed).įix corner-case errors and loss of precision when raising numeric values to very large powers (Dean Rasheed).In numeric multiplication, round the result rather than failing if it would have more than 16383 digits after the decimal point (Dean Rasheed) Reject cases where a query in WITH rewrites to just NOTIFY (Tom Lane) The end result would be a null-pointer dereference in the executor.

GROUP BY GROUPING SETS (()) FOR UPDATE (Tom Lane) Disable the feature altogether on OpenSSL versions that permit doing so, which are 1.1.0h and newer. A maliciously crafted renegotiation request could result in a server crash (see OpenSSL issue CVE-2021-3449). SSL renegotiation has been disabled for some time, but the server would still cooperate with a client-initiated renegotiation request.
Disallow SSL renegotiation more completely (Michael Paquier)
