Alejandro Do Nascimento Mora	c4ac6d810f	Use DefaultQueryExecMode in CopyFrom ... CopyFrom had to create a prepared statement to get the OIDs of the data types that were going to be copied into the table. Every COPY operation required an extra round trips to retrieve the type information. There was no way to customize this behavior. By leveraging the QueryExecMode feature, like in `Conn.Query`, users can specify if they want to cache the prepared statements, execute them on every request (like the old behavior), or bypass the prepared statement relying on the pgtype.Map to get the type information. The `QueryExecMode` behave exactly like in `Conn.Query` in the way the data type OIDs are fetched, meaning that: - `QueryExecModeCacheStatement`: caches the statement. - `QueryExecModeCacheDescribe`: caches the statement and assumes they do not change. - `QueryExecModeDescribeExec`: gets the statement description on every execution. This is like to the old behavior of `CopyFrom`. - `QueryExecModeExec` and `QueryExecModeSimpleProtocol`: maintain the same behavior as before, which is the same as `QueryExecModeDescribeExec`. It will keep getting the statement description on every execution The `QueryExecMode` can only be set via `ConnConfig.DefaultQueryExecMode`, unlike `Conn.Query` there's no support for specifying the `QueryExecMode` via optional arguments in the function signature.	2022-12-23 13:22:26 -06:00
