Hi Hackers,

PFA patch for RM#3289 where decode error was thrown on querying a SQL_ASCII database table. Please note, this problem occurs only on windows.

Sample insert - insert into test_tab values ('é');

psycopg2 has a encodings dictionary where Postgres Database Encodings are mapped to python equivalent. It uses 'ascii' decoder of python to decode for SQL_ASCII encoding. If data has characters beyond the limit of ascii then it failed. The solution would be to use utf_8 decoder instead of ascii. I tried setting the client_encoding using set_client_encoding('UTF8') method of a psycopg2 connection but no luck (also its not allowed for async connection). I also tried executing "SET CLIENT_ENCODING='UTF8'" but it didn't work too.

So, as in the patch, I had to set encodings dict value directly to 'utf_8' and it seems to be working. Please note, the same is added to psycopg3 milestones

https://github.com/psycopg/psycopg2/milestone/4

Also fixed a small glitch for sql editor connection status check.

Kindly review.

Thanks and Regards,
