Bump postgresql from 42.2.15 to 42.2.18

[dependabot]

Bumps postgresql from 42.2.15 to 42.2.18.

Changelog

Sourced from postgresql's changelog.

[42.2.18]

Fixed

• Unfortunately changing the default of gssEncMode to ALLOW was not enough. The GSSEncMode Enum was not changed as well fixed in #1920

[42.2.17]

Changed

• Change default of gssEncMode to ALLOW. PostgreSQL can deal with PREFER but there are cloud providers that did not implement the protocol properly. Libpq gets around this by checking for a GSS credential cache before attempting the connection. This is possible in JDK 8 and up, but not JDK6, or JDK7 fixes Issue #1868 [PR #1913](pgjdbc/pgjdbc#1913)

Added

• Add smallserial metadata [PR #899(pgjdbc/pgjdbc#899)

Fixed

• Avoid NullPointerException when receiving PGbox, PGcircle, PGline, PGlseg, PGpath, PGpoint, PGpolygon, and PGmoney [PR 1873] (pgjdbc/pgjdbc#1873).
• The driver returns enum and jsonb arrays elements as String objects (like in 42.2.14 and earlier versions) PR 1879.
• PgTokenizer was ignoring last empty token [PR #1882](pgjdbc/pgjdbc#1882)
• Remove osgi from karaf fixes Issue #1891 [PR #1902](pgjdbc/pgjdbc#1902)

[42.2.16] (2020-08-20)

Known issues

• The driver returns enum and jsonb arrays elements are returned as PGobject instances (fixed in 42.2.17)

Fixed

• Arrays sent in binary format are now sent as 1 based. This was a regression for multi-dimensional arrays as well as text/varchar, oid and bytea arrays. Since 42.2.0 single dimensional arrays were stored 0 based. They are now sent 1 based which is the SQL standard, and the default for Postgres when sent as strings such as '{1,2,3}'. Fixes issue 1860 in PR 1863.
