Jack Christensen a262126b5c Replace IsAlive with IsClosed 
IsAlive is ambiguous because the connection may be dead and we do not
know it. It implies the possibility of a ping. IsClosed is clearer -- it
does not promise the connection is alive only that it hasn't been
closed.

Jack Christensen 6972a57421 pgtype.OID type should only be used for scanning and encoding values 
It was a mistake to use it in other contexts. This made interop
difficult between pacakges that depended on pgtype such as pgx and
packages that did not like pgconn and pgproto3. In particular this was
awkward for prepared statements.

This is preparation for removing pgx.PreparedStatement in favor of
pgconn.PreparedStatement.

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 a6bdd8fd49 Hard code standard PostgreSQL types 
Instead of needing to instrospect the database on connection preload the
standard OID / type map. Types from extensions (like hstore) and custom
types can be registered by the application developer. Otherwise, they
will be treated as strings.

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.

Prefix types in namespaces other than pg_catalog or public
 2017-09-14 13:59:51 -05:00
Kelsey Francis 953e08df99 Prefix types in namespaces other than pg_catalog or public 
It's possible to define a type (e.g., an enum) with the same name in two
different schemas. When initializing data types after connecting, types
defined within schemas other than pg_catalog or public should be
qualified with their schema name to disambiguate them and ensure all
types with the same base name get added to the map of OID to type.

Prior to this commit, the last type scanned would "win", and all others
with the same name would be missing from the ConnInfo type maps, which
would subsequently cause any PREPARE involving columns of those missing
types to return the error "unknown oid".

Kelsey Francis ea740fb316 Fix some invalid one round trip execs failing to return non-nil error 
Prior to this commit, execEx() would write the one round trip exec to
the connection before first calling ensureConnectionReadyForQuery, which
ultimately caused any errors to be suppressed if the exec followed a
valid query, because the receive message processing would finish
successfully as soon as it received the ReadyForQuery that actually
belonged to the preceding query. So, the exec would never actually
receive the error message that it caused, leaving it to be incorrectly
received by the first subsequent query sent.

Jack Christensen 5eb19bc66a Add *Conn.CopyFrom 
This replaces *Conn.CopyTo. CopyTo was named incorrectly. In PostgreSQL
COPY FROM is the command that copies from the client to the server. In
addition, CopyTo does not accept a schema qualified table name. This
commit introduces the Identifier type which handles multi-part names and
correctly quotes/sanitizes them. The new CopyFrom method uses this
Identifier type.

Conn.CopyTo is deprecated.
