SQL functions depracated

[webb-ben]

It appears that a significant portion of the functions in the Liquibase configuration are deprecated. @dblodgett-usgs @gzt5142 (cc: @EthanGrahn) I would be interested to know if we can prune what is no longer used.

It is my understanding that most of the nhdplus_navigation functions have been superseded with mybatis.

Then it appears that neither nldi-crawler or nldi-crawler-py use any of the nldi_data functions.

I believe there are legacy API calls that still rely on a few of the functions. There are also navigation calls that rely on certain plpgsql features (I think it was looping and/or recursive calls) that I wasn't able to migrate to mybatis. I'd be wary of migrating the navigation if mybatis doesn't support it because I found the plpgsql functions to be far faster than trying to work around it in mybatis.

[dblodgett-usgs]

I would support dropping anything that isn't called by the new functions.
