bugfix: validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: need to escape the quotes in \set ... 'SALVIAS'

validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: removed `SET search_path TO public;` since this is the default

validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: search_path: removed public_validations since we are not creating views

validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: use psql var :datasource instead of current_schema() so that the queries are runnable without special configuration of the search_path

validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: removed `CREATE OR REPLACE VIEW` so the validations views are not unintentionally replaced when running this file

validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: updated from DB

bugfix: *.sql: public.source_by_shortname(): need to wrap it in a nested SELECT because Postgres incorrectly does not constant-fold (inline) it, leading to a slowdown when it is therefore run many times. this is done using the steps at wiki.vegpath.org/Postgres_queries#wrap-function-call-in-nested-SELECT .

fix: validation/aggregating/plots/SALVIAS/bien3_validations_salvias_db_original.VegCore.sql: renamed truncated views to match the output queries

bugfix: validation/aggregating/plots/SALVIAS/bien3_validations_salvias_db_original.VegCore.sql: can't double-JOIN like in MySQL (`JOIN a JOIN b ON a_conds AND b_conds`), so split double-JOIN into two JOINs w/ own ON clauses

validation/aggregating/plots/SALVIAS/bien3_validations_salvias_db_original.VegCore.sql: removed `LIMIT 10` to match output queries
