bugfix: schemas/vegbien.sql, validation/aggregating/specimens/qualitative_validations_specimens.sql: _specimens_10_count_number_of_records_by_institution: need to dereference specimenreplicate.duplicate_institutions_sourcelist_id to the corresponding sourcelist.name

schemas/vegbien.sql: public_validations._specimens_*: added comments from validation/aggregating/specimens/qualitative_validations_specimens.sql

schemas/vegbien.sql: remake_diff_tables(schema text): removed bien2_traits runtime because this applies only to one datasource. the bien2_traits runtime is now documented in inputs/bien2_traits/run.

schemas/vegbien.sql: public_validations: schema comment: documented how to run the validations. this information is also in the usage comment for public_validations.remake_diff_table(), but is copied here for easy reference.

schemas/vegbien.sql: public_validations: specimens queries: added autogenerated ~type tables

schemas/vegbien.sql: public_validations: added specimens queries to pipeline

fix: schemas/vegbien.sql: public_validations.rematerialize_out_view(text, regclass): run with join_collapse_limit = 1 to fix query planner issues. this option has been tested on the queries that do not yet use the standard join sequence (plots #11,12,13,14,16,17,18), and all of these queries also work fine with join_collapse_limit = 1. (the standard join sequence is used to ensure both correctness of the query and compatibility with join_collapse_limit = 1, but in some cases is not needed for join_collapse_limit.)

bugfix: schemas/vegbien.sql: schemas/vegbien.sql(): need to util.use_schema(schema_anchor) before initializing vars that use own-schema functions

*{.sh,run}: runscript targets: use begin_target instead of echo_func so the target name is properly echoed. note that this requires using with_rm so that $rm is properly progagated to applicable invoked targets. (previously, $rm was progagated to all invoked targets. note that with_rm only works inside a runscript target that starts with begin_target.)

schemas/vegbien.sql: updated _specimens_01_count_of_total_records_specimens_in_source_db
