ToDo: API for SQL statement execution other than SPI

Hi

I am writing two background workers - autoreindex and scheduler. In Both I need to execute queries from top level. I had to wrote redundant code   https://github.com/okbob/autoreindex/blob/master/utils.c autoreindex_execute_sql_command .Same code is in pglogical. Some statements - like VACUUM or REINDEX CONCURRENTLY is not possible call from SPI.

Can be nice to have this function in core.

Regards

Pavel

I strongly agree. In particular, something that can clean up and recover from ERRORs. Right now you have to borrow a bunch of PostgresMain.

pg_background handles this.  Somebody might want to resurrect that patch.

Here is the link for that patch, which works with 9.5
