Proget docker delete manifest api request fails

[andrey-ne_7936]

I'm trying to delete old docker manifests from proget, so i request DELETE /v2/${repo}/manifests/${digest} with header AUTHENTICATION: BASIC ${base64('api:myapikey')}, where digest is taken from 'docker-content-digest' header of manifest request. Like in docs.
Proget server returns error:
500: {"errors":[{"code":"UNKNOWN","message":"XX000: failed to find conversion function from unknown to text","detail":[]}]}
It looks like postgres problem.
Will it disappear if we move on MSSQL?

Proget 5.2.22 (Build 4) installed in docker
Postgres 9.5

I think so; that's a Postgres error message.

We deprecated Postgres a long while back, and new features aren't tested against Postgres database code.

Ok, thank you!
