Fixes the following vulnerabilities:
- CVE-2026-2003:
Improper validation of type "oidvector" in PostgreSQL allows a
database user to disclose a few bytes of server memory. We have not
ruled out viability of attacks that arrange for presence of
confidential information in disclosed bytes, but they seem unlikely.
Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are
affected.

- CVE-2026-2004:
Missing validation of type of input in PostgreSQL intarray extension
selectivity estimator function allows an object creator to execute
arbitrary code as the operating system user running the database.
Versions before PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are
affected.

- CVE-2026-2005:
Heap buffer overflow in PostgreSQL pgcrypto allows a ciphertext
provider to execute arbitrary code as the operating system user
running the database. Versions before PostgreSQL 18.2, 17.8, 16.12,
15.16, and 14.21 are affected.

- CVE-2026-2006:
Missing validation of multibyte character length in PostgreSQL text
manipulation allows a database user to issue crafted queries that
achieve a buffer overrun. That suffices to execute arbitrary code as
the operating system user running the database. Versions before
PostgreSQL 18.2, 17.8, 16.12, 15.16, and 14.21 are affected.
