-- If I did have a postzon changes file, it'd most likely be best to import the data directly and use postgis to do our conversion
-- as the data is selected out of the data_stage table (rather than using the convert_paf.pl script). We could get those fields with
-- something like:
- -- CASE WHEN substring(northing,1,1) ~ '[\x4f-\x5a]' THEN '1' || translate(northing, 'POUTZY', '221100') ELSE northing END || '0' AS f_notrhing,
+ -- CASE WHEN substring(northing,1,1) ~ E'[\x4f-\x5a]' THEN '1' || translate(northing, 'POUTZY', '221100') ELSE northing END || '0' AS f_notrhing,
-- ST_x(ST_transform(ST_GeomFromText('POINT('||easting||' '||f_northing||')',CASE WHEN postcode LIKE 'BT%' THEN 29903 ELSE 27700 END),4326)) AS longitude,
