On 29th of November 2018, Alvaro Herrera committed patch:
Add log_statement_sample_rate parameter
This allows to set a lower log_min_duration_statement value without
incurring excessive log traffic (which reduces performance). This can
be useful to analyze workloads with lots of short queries.

On 10th of March, Magnus Hagander committed patch:
Report pg_hba line number and contents when users fail to log in
Instead of just reporting which user failed to log in, log both the
line number in the active pg_hba.conf file (which may not match reality
in case the file has been edited and not reloaded) and the contents of
the matching line (which will always be correct), to make it easier
to debug incorrect pg_hba.conf files.
The message to the client remains unchanged and does not include this
information, to prevent leaking security sensitive information.
