Bad Request when installing command line tool on Ubuntu

[levinotik]

I am following the instructions here and am getting a 400. Any ideas on how to resolve that?

Actually, could I just install the command line tool outside of the DB server? In my case, I'm running PG in a Docker container. If I'm able to run the CL tool on the host machine (my Mac), I can just do that.

[levinotik]

make and make install seemed to succeed on the DB server, but then when running dexter on the host machine, I get:

> tail -F -n +1 my-log-file | dexter -h localhost -p 5432 -U # and so on....
Install HypoPG first: https://github.com/ankane/dexter#installation

Hey @levinotik, for the 400 error, it looks like $VERSION_ID is 9 when it should be something like 20.04. What does cat /etc/os-release show?

Also, the command line tool can be run on a separate machine from the database server, but the HypoPG extension needs to be installed on the database server (the make commands need to be run there).

[levinotik]

Thanks for the reply @ankane Looks like 9 is correct though:

root@db:/tmp/hypopg-1.3.1# cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 9 (stretch)"
NAME="Debian GNU/Linux"
VERSION_ID="9"
VERSION="9 (stretch)"
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

In any event, I did install the CL tool on the host machine and installed HypoPG (seemingly successfully) on the DB server, but still get that error Install HypoPG first: https://github.com/ankane/dexter#installation

It looks like you're on Debian, so you'll want to follow the Debian instructions.

For HypoPG, try using psql to connect to the DB server with same credentials you're passing to Dexter and running the following to verify that it's installed:

SELECT * FROM hypopg_list_indexes;

(should return 0 rows)

[levinotik]

@ankane hah I did realize that after I sent. Hadn't realized that HypoPG was available as a package using the PGDG packages, thanks a lot!

[levinotik]

SELECT * FROM hypopg_list_indexes; does return 0 rows now and everything seems to be setup correctly. When tailing the logs, all I see is Processing 0 new query fingerprints.

Update: installed Dexter on the DB container and seems to be working now!

Great, glad it's working!
