Yes, you can remove all non-ASCII string values or those in non-English locales from the database in PostgreSQL using the following steps:
First, create a new database backup before performing any deletion operations.
Use the following SQL query to identify all rows with non-ASCII characters in a particular column:
SELECT * FROM my_table WHERE my_column ~ '[^[:ascii:]]';
Replace my_table
with the name of your table and my_column
with the name of the column you want to search.
DELETE FROM my_table WHERE my_column ~ '[^[:ascii:]]';
Again, replace my_table
with the name of your table and my_column
with the name of the column you want to delete rows from.
DELETE FROM my_table WHERE my_table::text ~ '[^[:ascii:]]';
This will convert the entire row to a text value and check for non-ASCII characters before deleting it.
Note: Be careful while deleting rows as this operation is irreversible. It is recommended to create a backup before deleting any data.
