This is somewhat cosmetic, since as long as you know what you are looking at, "10.0" is a serviceable substitute for "10". But there is a potential for confusion between version numbers with minor numbers and those without --- we don't want people asking "why is psql saying 10.0 when my server is 10.2". Therefore, back-patch as far as practical, which turns out to be 9.3. I could have redone the patch to use fprintf(stderr) in place of psql_error(), but it seems more work than is warranted for branches that will be EOL or nearly so by the time v10 comes out. Although only psql seems to contain any code that needs this, I chose to put the support function into fe_utils, since it seems likely we'll need it in other client programs in future. (In 9.3-9.5, use dumputils.c, the predecessor of fe_utils/string_utils.c.) In HEAD, also fix the backend code that whines about loadable-library version mismatch. I don't see much need to back-patch that.
