* Remove docker action and update dockerfile

* Enable all compilation flags (npoint, cbuffer, pose) in docker image

Fixes the issue mentioned by #680.

The commutators of the temporal compops for the `ttext` were wrong.
Previously this didn't raise an error, but starting with PG 17, postgres
raises an error when two operators have the same commutator. Strangely,
this error was only raised when running `pg_upgrade` to go from PG 16 to
PG 17, and does not get raised when running `CREATE INSTALL`.

Cherry-pick of c2c5608

-  Removes any existing PostgreSQL installations
- Sets a consistent port (PGPORT=5432)

Update the calls to `vacuum_delay_point`, which took an additional
parameter in PG 18.

Couldn't cherry pick these changes from master as they were part of a
larger commit.

The only SQL change between 1.2.0 and 1.2.1 are the commutator fixes
from 5e410dc. This commit adds an upgrade file that can be used to go
from 1.2.0 to 1.2.1 by dropping and recreating the needed operators.
This file gets installed together with the rest of the files during
`make install`. To upgrade, run the following command after having build
and installed 1.2.1:

```
ALTER EXTENSION mobilitydb UPDATE TO "1.2.1";
```

Cherry-picked from master.
