PostgreSQL 13 compatibility.

Also try to log tail of PG logs on CI in a brave hope of catching troubles
there. Currently travis job on 10 rarely fails at test_concurrent_updates, but
we've failed to reproduce the issue locally. Note that test_concurrent_updates
actually doesn't perform anything useful as testgres nodes aren't pickable due
to weird logging implemented in separate thread, but nobody cared to check
apply_async result so this has went unnoticed for a long time.

 ### NOTE: this project is not under development anymore
 
-`pg_pathman` supports Postgres versions [9.5..12], but most probably it won't be ported to 13 and later releases. [Native partitioning](https://www.postgresql.org/docs/current/ddl-partitioning.html) is pretty mature now and has almost everything implemented in `pg_pathman`'; we encourage users switching to it. We are still maintaining the project (fixing bugs in supported versions), but no new development is going to happen here.

 # pg_pathman
 
 The `pg_pathman` module provides optimized partitioning mechanism and functions to manage partitions.
 
 The extension is compatible with:

+ * PostgreSQL 9.5, 9.6, 10, 11, 12, 13;
  * Postgres Pro Standard 9.5, 9.6, 10, 11, 12;
  * Postgres Pro Enterprise;
