inputs/.geoscrub/geoscrub_output/postprocess.sql, run: updated runtimes

inputs/.geoscrub/geoscrub_output/run: documented full load_data() runtime (9 min @starscream)

inputs/.geoscrub/geoscrub_output/postprocess.sql: updated runtimes for refreshed data, which now has 4x as many rows (1,707,970->6,747,650)

inputs/.geoscrub/geoscrub_output/: refreshed geoscrub data. removed +header.csv because the extract now contains the header in the first row of the file.

bugfix: lib/sh/local.sh: psql(): $is_root: use `` around case statement instead of $(), because it contains an embedded unbalanced )

bugfix: inputs/.geoscrub/geoscrub_output/geoscrub.csv.run: include only the columns that Jim provided in his extract (the geoscrub table contains additional internal columns that are not part of the geovalidation data for VegBIEN). documented runtime (30 s) and upload time (1.5 min).

inputs/.geoscrub/geoscrub_output/geoscrub.csv.run: removed no longer needed setting of $local_server, $local_user (and use of $local_pg_database instead of $database) because the use_local bug in local.sh has been fixed

bugfix: lib/sh/local.sh: psql(): don't default the connection vars using use_local if running as the postgres user. in that case, connection must happen via a socket, with server="", and as the user running the command (postgres), with user="".

bugfix: inputs/.geoscrub/geoscrub_output/geoscrub.csv.run: need to manually set local_server, local_user to "" so that they do not default to their bien-user values

bugfix: lib/sh/db.sh: avoid outputting to /dev/fd/# when running as sudo on Linux, because this causes a "Permission denied" error (due to the /dev/fd/# file being owned by a different user). this is not a problem with normal redirects (>&#), because they do not use /dev/fd/# files which can have access permissions.
