Problem:
The current command "postgresql_lsp" doesn't work as expected because
the server requires the "lsp-proxy" argument to function properly.
Solution:
Update the cmd to use ("postgresql_lsp", "lsp-proxy") to correctly
invoke the language server with its required arguments.
Problem:
The name `server_configurations` is extremely verbose and irritatingly
formal and dogmatic. This overlong name is a constant nuisance when
reading, writing, and coding.
It's also not even correct: these configurations are just as much
"client" configurations as they are "server" configurations.
Solution:
- Rename to a shorter name.
- Leave placeholder files for any old URLs that link to the old
location.
