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.

bugfix: lib/runscripts/util.run: to_top_file(): need to pass "$@" to to_file

lib/runscripts/util.run: to_top_file: added function for this (in addition to alias), so that this can be run from sudo in a wrap_fn command

lib/sh/db.sh: pg_as_root(): run sudo with echo_run to help debug

bugfix: lib/sh/db.sh: pg_cmd(): only set PG* connection/login env vars when the corresponding var is non-empty. there are some situations in which these must be unset (in order to use the default value), and other situations when the var must be set to something (i.e. "") to avoid it being defaulted to a value in local.sh > connection vars.

backups/TNRS.backup.md5: updated

bugfix: inputs/.geoscrub/geoscrub_output/geoscrub.csv.run: need to set $local_pg_database instead of $database because use_local (in psql()) does not currently avoid clobbering already-set versions of the applicable env vars
