On 26th of November 2018, Tom Lane committed patch:
Add CSV table output mode in psql.
"\pset format csv", or --csv, selects comma-separated values table format.
This is compliant with RFC 4180, except that we aren't too picky about
whether the record separator is LF or CRLF; also, the user may choose a
field separator other than comma.
This output format is directly compatible with the server's COPY CSV
format, and will also be useful as input to other programs. It's
considerably safer for that purpose than the old recommendation to
use "unaligned" format, since the latter couldn't handle data
containing the field separator character.

tweaking by me

On 28th of April, Greg Stark committed patch:
Add support for wrapping to psql's "extended" mode. This makes it very
feasible to display tables that have both many columns and some large
data in some columns (such as pg_stats).

Every now and then someone asks, on irc or mailing lists, some question which shows deep misunerstanding (or lack of understanding) of timestamps – especially the ones with time zones.
Since I got bitten by this before, let me describe what timestamps are, how to work with them, and what are the most common pitfalls that you can encounter.

On 21st of November Robert Haas committed new patch, which adds new function:
Add new SQL function, format(text).
Currently, three conversion format specifiers are supported: %s for a
string, %L for an SQL literal, and %I for an SQL identifier. The latter
two are deliberately designed not to overlap with what sprintf() already
supports, in case we want to add more of sprintf()'s functionality here
Patch by Pavel Stehule, heavily revised by me. Reviewed by Jeff Janes
and, in earlier versions, by Itagaki Takahiro and Tom Lane.
