I wanted to drop a quick note thanking the developers who have contributed to Postgres. I have recently upgraded our production PG instances from pg9.3 to pg11.

We do a lot of table syncs, and we have one process at the end of the month that syncs 3 very large tables (400GB). This sync happens from a shell script using pg_dump and pg_restore, we have it set to use -j3 but it's called sequentially so it never really takes advantage of parallel.

Since pg11 on both the target and source, the run time has decreased a lot, I chalk it up to the parallel index creations in pg11 which was a very time consuming process on pg9.3.
The process has finished almost 10 hours earlier than pg93. So thank you for your hard work and dedication to this awesome piece of software.
