Workspace required vs single file support

[igorlfs]

Hello,

I'm using this with neovim. I use multiple SQL dialects, which lead me to the following situation: sometimes I'm working on a directory that does not use Postgres and the server starts anyway. From what I can tell, the server is not really useful in this scenario, so perhaps it shouldn't be started at all? Please, let me know if that's not the case.

The server attaches because the default neovim configuration does not enable workspace_required (previously, this setting was called single_file_support, which meant the opposite). Locally, I can override this configuration and only have the server attaching if neovim finds a postgres-language-server.jsonc. However, I was wondering if it makes sense to update the default configuration for neovim, so that others can "benefit" from this as well.

So, my question is: should the server attach to "single files" (i.e., even if a postgres-language-server.jsonc is not found), which is the current behavior with neovim, or should it only attach if a postgres-language-server.jsonc is found?

I traced down the original commit that initially set single_file_support, I'm not sure if it takes into account the scenario I described.
