Strange database retention error

[opsecx]

Came across what seems to be some artifact error in the configs. This is the situation:

I worked previously with another db in my postgres installation. The network upgraded and I switched db to a newly created one in the .env file. No traces of referring the older db (named "undexer" for these purposes). Things also index fine except for the crash mentioned in separate issue. Everything is indexed to the new db (let's call it undexer2). Now, when I delete the former db (undexer), I get the following errors when starting the indexer:

`./undexer index

When I recreate a dummy (empty, no permissions) db "undexer" again, it starts with no issues and indexes to "undexer2" all relevant data. I assume somehow somewhere in the build system, old .env data is retained. The old db is not referenced anywhere in current .env.
