Jack Christensen 9c5dfbdfb3 pgconn.CommandTag is now an opaque type 
It now makes a copy instead of retaining driver memory. This is in
preparation to reuse the driver read buffer.

Jille Timmermans 1d606a91b8 Change constant definition syntax so they show up in godoc 
for TxAccessMode, TxDeferrableMode and TxIsoLevel

After this commit, Godoc understands these are the valid values of these
types and shows them together in the documentation.

Jack Christensen 15ea38aae5 Document interfaces that may have methods added in the future 2019-10-12 09:35:29 -05:00
Jack Christensen 143bc3165d Add Conn() to Tx interface. 
This is necessary to allow code using a Tx to access the *Conn (and
pgconn.PgConn) on which the Tx is executing.
 2019-10-12 09:35:29 -05:00
Jack Christensen c0a1f9976a Conn.Begin and Conn.BeginTx return a Tx interface 
This is necessary for the Conn.Begin method to signature as other
methods that begin a transaction. This is technically a breaking change
but practically is just a bug fix that is extremely unlikely to break
any existing code.

Jack Christensen 3675337e5b Update for rename of pgconn.PreparedStatementDescription 2019-08-24 20:44:56 -05:00
Jack Christensen 31705e586a Use pgconn.PreparedStatementDescription directly 
Instead of having similar pgx.PreparedStatement
 2019-08-24 14:29:05 -05:00
Jack Christensen 99e5461522 Add pgx.Tx interface and pseudo nested transaction support 
This complicates the idea of a persistent transaction status and error
so that concept was removed.

Jack Christensen c3e41872a8 Resplit Begin and BeginEx 
This is in preparation for a Begin / Tx interface that will similate
nested transactions with savepoints.

In addition, this passes the TxOptions struct by value and thereby
removes an allocation.

Jack Christensen 66625e6489 Prepare takes context 
Also remove PrepareEx. It's primary usage was for context. Supplying
parameter OIDs is unnecessary when you can type cast in the query SQL.
If it does become necessary or desirable to add options back it can be
added in a backwards compatible way by adding a varargs as last
argument.

Jack Christensen dc699cefc7 Conn.CopyFrom takes context 2019-04-20 11:38:23 -05:00
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.
