fix: lib/util.py: dict_subset(): raise an error if collections.OrderedDict isn't available, because some callers may depend on this. note that using dict instead of OrderedDict may be the cause of the joining on the wrong columns bug (issue #902).

bugfix: lib/runscripts/validations.pg.sql.run: updated to reflect that validations.sql is now located inside a subdir, not the datasrc dir

fix: lib/runscripts/file.pg.sql.run: removed include of in_datasrc_dir.run, because this location does not apply to all .sql export scripts

lib/runscripts/validations.pg.sql.run: export_(): make the export idempotent for easier re-runnability

bugfix: lib/sh/db.sh: pg_dump(): need use_pg to import $pg_database before checking for existence of $database

lib/sh/util.sh: import_vars: documented that it's idempotent

bugfix: benign_does_not_exist_error(): removed ignore_e=3, because this exit status is also used for other errors

fix: lib/sh/db.sh: benign_does_not_exist_error(): use benign_error=1, which is now supported properly by stderr_matches()

bugfix: lib/sh/util.sh: stderr_matches(): support $benign_error properly, by handling exit status logging in this func instead

bugfix: lib/sh/db.sh: pg_schema_exists(): also need to benignify "does not exist" error if returns false

bugfix: lib/sh/util.sh: stderr_matches(): need to separately display errors that were incorrectly suppressed due to $benign_error

bugfix: lib/sh/util.sh: is_err(): rethrow must be inverted (rethrow->false if error)

fix: lib/sh/db.sh: pg_schema_exists(): display the function name so it's clear which function is running the psql commands

lib/sh/util.sh: split_lines(): usage: matched up and synced different syntaxes

bugfix: lib/sh/util.sh: log_msg!(): split_lines does not support being invoked by wrapper; need to use `declare lines; wrapper "split_lines" str` instead

fix: lib/sh/util.sh: split_lines(): usage: documented different syntax for when using wrapper

bugfix: lib/sh/util.sh: die_error_hidden(): echo_func to assist debugging

bugfix: lib/sh/util.sh: split(): need to limit the effects of IFS to just the splitting, so it doesn't cause strange errors in other functions

bugfix: stderr2stdout(): fd 2 must be redirected back to fd 2, not log-filtered, in case there are other errors in addition to the benign error. this fixes a bug in pg_schema_exists(), where errors about the DB being down were not displayed because they were log-filtered out.

bugfix: lib/sh/make.sh: begin_target: don't echo_func twice

bugfix: lib/runscripts/util.run: a non-runscript should have all args passed to main(). this fixes a bug in backups/*_snapshot where "main" would need to be prepended to any args for the script to run correctly.

bugfix: lib/runscripts/util.run: $wrap_fn: invoked script must always run as runscript so that wrapped command is run

lib/runscripts/util.run: added $is_runscript, for use by $wrap_fn

lib/sh/db.sh: added pg_start_backup(), pg_stop_backup()

lib/sh/db.sh: psql(): only set redirs if can redirect

bugfix: lib/sh/db.sh: psql(): don't use `--file /dev/fd/40` when can't redirect

fix: lib/sh/db.sh: psql(): when using sudo with custom $stdin, raise error that this is not supported

lib/sh/db.sh: psql(): $data_bypasses_filter: renamed to $data2stdout for clarity

lib/sh/db.sh: psql(): $bypass_ok: renamed to $can_redir for clarity

lib/sh/db.sh: mysql_snapshot(): use new db_snapshot()

lib/sh/sync.sh: added db_snapshot()

lib/sh/db.sh: mysql_snapshot(): for large files, don't re-copy entire file

lib/sh/db.sh: mysql_snapshot(): use live mode as the default

fix: lib/sh/db.sh: mysql_snapshot(): need to create dest dir if doesn't exist

bugfix: lib/sh/db.sh: mysql_snapshot(): try: need to use split syntax with prep_try instead, to work with prefix vars

fix: lib/sh/util.sh: try usage: documented that the split syntax with prep_try is meant to be used with vars before the cmd

fix: lib/sh/util.sh: echo_vars(): also need to print unset vars (including unset kw_params)

lib/sh/util.sh: echo_vars(): put loop var on same line as `for`

bugfix: lib/sh/util.sh: redir(): need to load new aliases before it

lib/sh/util.sh: echo_redirs_cmd(): log $PATH to facilitate troubleshooting

lib/sh/util.sh: echo_redirs_cmd(): documented what the $(...) section does

lib/sh/util.sh: moved echo_redirs_cmd() to right before redir() which uses it

lib/sh/util.sh: catch(): log at higher log_level, since this is internal code

fix: lib/sh/util.sh: die_e(): treat SIGPIPE as benign error
