mappings/VegCore-VegBIEN.csv: Removed _date/date, because _date using a string date argument is no longer supported under plpython3u (dateutil is missing). Note that PostgreSQL's own date parsing is sufficient for most dates, so this use of _date is not strictly necessary and removing it will improve import times.

schemas/py_functions.sql: Replaced xrange() with range() for plpython3u

root Makefile: Python: python-Linux: Also install python3, needed by plpython3u

schemas/py_functions.sql: Updated except clause syntax for PostgreSQL 9.1.6

schemas/*.sql: Updated for PostgreSQL 9.1.6, which has standard_conforming_strings = on (which affects \-escapes in string literals), escape_string_warning not explicitly set, and uses ALTER TABLE ONLY instead of ALTER TABLE

README.TXT: Removed step to manually run make_analytical_db, now that this is done automatically by import_all. Added separate instructions to remake the analytical DB.

import_all: Change to main directory make targets are run from. Use relative paths to bin/ commands, which is possible now that the current dir is set.

import_all: Create a background process that waits until the import is done and then runs make_analytical_db

Added waitpid

import_all: Documented that `wait %1` waits for asynchronous commands
