lib/sh/db_make.sh: added pg_export_table_to_dir(), pg_export_tables_to_dir(). unlike db.sh pg_export_table_to_dir_no_header(), these functions are make-aware and will not clobber an existing file.

reran inputs/test_taxonomic_names/test_scrub, which generates the public.test_taxonomic_names sample schema

inputs/CTFS/Plot/map.csv: DescriptionOfSite: remapped to locationRemarks, not locality

inputs/CTFS/AggregateObservation/: translated multi-column filters to postprocessing derived columns, using the steps at wiki.vegpath.org/Adding_new-style_import_to_a_datasource#Translating-filters-to-postprocessing-derived-columns

schemas/vegbien.sql: geoscrub_input_new: updated for VegCore-renamed geoscrub_output column names

schemas/util.sql: added ?>= operator with is_more_complete_than() function

inputs/.geoscrub/: switched to new-style import, using the steps at wiki.vegpath.org/Adding_new-style_import_to_a_datasource

inputs/.geoscrub/geoscrub_output/: translated single-column filters to postprocessing derived columns, using the steps at wiki.vegpath.org/Adding_new-style_import_to_a_datasource#Translating-filters-to-postprocessing-derived-columns

schemas/util.sql: SQL-language IMMUTABLE functions marked STRICT: removed STRICT to enable dynamic inlining, which speeds up the function up to 7x. STRICT was not removed where the function was particularly complex and the STRICT optimization would likely be more significant than inlining.

bugfix: inputs/BRIT/specimen_flat/postprocess.sql: diameterBreastHeight_cm, height_m: use newly NULL-mapped versions of columns instead of the *_verbatim columns
