chore: remove editor backup files #1255
These are removed by the Debian package build in the "clean" step and
On a side node, the "92" and "93" directories in the doc/documentation directory are identical and could be merged, and documentation.md in the same place has dangling references to versions 80 till 91.
LGTM. Is the PR "feature complete"? Do you intend to remove more files?
Technically speaking we might want to update documentation build system so it creates proper cross-references for various pgdbc versions. However I haven't heard if anyone wanted to do that.
