sql.py: parse_exception(): function MissingCastException: Don't match quotes around the function name because this particular exception (incorrect param type) does not include them. Casts to regproc, which also produce a DoesNotExistException, include the quotes but do not indicate a MissingCastException.

sql.py: parse_exception(): function MissingCastException: Fixed bug where the 1st param's type in the exception's function signature is not actually the type the argument needs to have, because this is just the argument's current type

sql.py: parse_exception(): typed_name_re: Also match identifiers without quotes, such as functions in "No function matches the given name and argument types" errors. This fixes a bug where DoesNotExistExceptions could not be parsed as MissingCastExceptions when applicable because the DoesNotExistException pattern would not even match.

inputs/.NCBI/: Renamed higher_taxa to nodes because it currently doesn't just contain the higher taxa

schemas/vegbien.sql: taxonlabel: taxonlabel_2_set_canon_label_id(): Only run if matched_label_id has actually changed, to avoid infinite recursion when updating canon_label_id on labels that resolve to this label when there are cycles in the data

inputs/.NCBI/: Renamed higher_taxa to nodes because it currently doesn't just contain the higher taxa

inputs/.NCBI/: Renamed higher_taxa to nodes because it currently doesn't just contain the higher taxa

inputs/.NCBI/: Renamed names, nodes to *.src so they wouldn't get an automatic row_num column and can be used in higher_taxa's join
