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)
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.
[42.2.15] (2020-08-14)
Known issues
The driver returns enum and jsonb arrays elements are returned as PGobject instances (fixed in 42.2.17)
Changed
Rename source distribution archive to postgresql-$version-jdbc-src.tar.gz, and add top-level archive folder ba017507
Add the ability to connect with a GSSAPI encrypted connection. As of PostgreSQL version 12 GSSAPI encrypted connections
are possible. Now the driver will attempt to connect to the server with a GSSAPI encrypted connection. If that fails then
attempt an SSL connection, finally falling back to a plain text connection. All of this is controlled using both the gssEncMode
and sslMode parameters which, in concert with pg_hba.conf, determine if a particular mode is allowed and or required. PR 1821ad921b9e
Source release archive shades dependencies (scram) by default. It affects only postgresql-version-src.tar.gz release artifact f0301eb9
