R: Error code associated to "could not open relation with OID ..."

I don't use temporary tables in my application.
>From a previous post I've understood that this error could happen if I'm trying to access a table whose corresponding row in the pg_class table is being modified. So I wanted to catch the error code of such exception to retry a second insert into the table.

It's usually down to a cached plan referring to a temporary table that's
being replaced. Could be a normal table being dropped/recreated though.

It could be a query-plan cached by your jdbc stuff or perhaps a plpgsql
function using TEMP tables?
