MyBatis Bump postgresql from 42.2.16 to 42.2.17

Sourced from postgresql's changelog.

[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)
