schemas/util.sql: added search_path_append()

schemas/util.sql: added eval() to allow running EXECUTE outside of a function (and to echo the command that is run)

inputs/GBIF/raw_occurrence_record_plants/run: added import() runtime (5 h)

inputs/GBIF/raw_occurrence_record_plants/run: table.tsv.gz/make() runtime: noted that this excludes the upload time

inputs/GBIF/raw_occurrence_record_plants/run: added table.tsv.gz/upload() runtime (15 min)

added lib/runscripts/mysql.table.run (general to all MySQL datasources) and use it in inputs/GBIF/table.run

inputs/GBIF/raw_occurrence_record_plants/run: table.tsv/make(): to view runtime when using `screen`: keys used to scroll: added Ctrl-B/Ctrl-F for page-at-a-time scrolling (there are a lot of pages of output for the import() target!)

bugfix: inputs/GBIF/table.run: table.tsv.gz/make(): don't run table.tsv.gz/upload in test mode, to avoid clobbering the backup of a full table.tsv with a partial, testing table.tsv

lib/sh/db.sh: set test mode when using limited # rows

bugfix: inputs/GBIF/table.run: table.tsv.gz/upload(): don't use inplace mode because it leaves a newer mtime when aborted, causing rsync to think that the partial upload is actually newer than the source. note that rsync's --partial-dir mode is just as capable of resuming an aborted upload (it will just use a file in .rsync-tmp instead). inplace mode is primarily designed for fixed-offset files which don't change much between edits, but this is not true for exports (or the gzips of them), which will change the file offsets of most data if even one row or column is added or removed.
