Jack Christensen 2bd26ec7fa Expose stdlib.Conn.Conn() to enable database/sql.Conn.Raw() 2020-05-30 13:27:25 -05:00
Jack Christensen a66b09fbd8 Improve simple protocol / text format 
Increased data type support for simple protocol. Improved test
coverage of simple protocol. This has the additional advantage of
exercising the text encoders and decoders.

Jack Christensen c44cda4bb4 Clean up old Go 1.10 build tags 
pgx requires Go modules which requires at least Go 1.11 so there is no
use in build tags to support older Go versions.

Jack Christensen 77c1076d39 stdlib.ReleaseConn closes connections left in invalid state 
If a connection is in a transaction or has an open result set then
close the connection when returning it to database/sql. When next
database/sql attempts to use it the connection will return
driver.ErrBadConn and database/sql will remove it from the pool.

Wow. This is fun. Sure is easy to get modules wrong when upgrading a v2+
project.

Jack Christensen c53c9e6eb5 Remove simple protocol and one round trip query options 
It is impossible to guarantee that the a query executed with the simple
protocol will behave the same as with the extended protocol. This is
because the normal pgx path relies on knowing the OID of query
parameters. Without this encoding a value can only be determined by the
value instead of the combination of value and PostgreSQL type. For
example, how should a []int32 be encoded? It might be encoded into a
PostgreSQL int4[] or json.

Removal also simplifies the core query path.

The primary reason for the simple protocol is for servers like PgBouncer
that may not be able to support normal prepared statements. After
further research it appears that issuing a "flush" instead "sync" after
preparing the unnamed statement would allow PgBouncer to work.

The one round trip mode can be better handled with prepared statements.

As a last resort, all original server functionality can still be accessed by
dropping down to PgConn.

James Hartig 6d336eccb1 Added LastStmtSent and use it to retry on errors if statement was not sent 
Previously, a failed connection could be put back in a pool and when the
next query was attempted it would fail immediately trying to prepare the
query or reset the deadline. It wasn't clear if the Query or Exec call
could safely be retried since there was no way to know where it failed.

You can now call LastQuerySent and if it returns false then you're
guaranteed that the last call to Query(Ex)/Exec(Ex) didn't get far enough
to attempt to send the query. The call can be retried with a new
connection.

This is used in the stdlib to return a ErrBadConn if a network error
occurred and the statement was not attempted.
