GA and LA TIGER TABBLOCK20 files fail to load for years 2020 through 2023

[weyhing]

Both Georgia and Louisiana have malformed TABBLOCK20 shapefiles (for 2020 through 2023 download years). These two states will not load into tiger_data tables inherited from tiger.tabblock20.

The problem is that each shapefile is missing a UATYPE20 column, and also has an unexpected GEOIDFQ20 column. These are the only two TABBLOCK20 shapefiles with this problem.

Considering the UATYPE20 column is as-of-yet unused I've worked around the problem by adding a couple lines of code to the ga_load.cmd and la_load.cmd scripts:

%PSQL% -c "ALTER TABLE tiger_staging.la_tabblock20 ADD COLUMN IF NOT EXISTS uatype varchar(1) null;"
%PSQL% -c "ALTER TABLE tiger_staging.la_tabblock20 DROP COLUMN IF EXISTS geoidfq20;"
