Jack Christensen fd7b776540 Merge pull request #323 from kelseyfrancis/namespace-oids 
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".

Jack Christensen 9eb21591ee Update sslmode docs 2017-09-09 11:05:39 -05:00
Johan Brandhorst 30fa7cc37f Skip certificate verification for sslmode "require" 
This more appropriately aligns the behaviour of the library with
that advertised by the postgres documentation.

According to the table on the official documentation page
https://www.postgresql.org/docs/current/static/libpq-ssl.html,
the "require" mode should be used when:

"I want my data to be encrypted, and I accept the overhead. I trust that the network will make sure I always connect to the server I want."

This maps reasonably well to a TLS config that skips certificate verification.

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 dcf3ee2781 Fix sendPreparedQuery write error hang 
If the Write call in sendPreparedQuery encountered a non-fatal error - which means it sent
no bytes. It still was marking the connection as not ready for query. That caused the next
call to hang.

In general, pgproto3 types should be used. But these functions may be easier to

Jack Christensen 2df4b1406b Do not double call termContext in QueryEx 
QueryEx was calling termContext and rows.fatal on err of sendPreparedQuery.
rows.fatal calls rows.Close which already calls termContext. This sequence of
calls was causing underlying io timeout errors to be returned instead of context
errors.

In addition, added fatalWriteErr helper method to allow recovery of write
timeout errors where no bytes were written.

This should solve flickering errors on Travis.

Jack Christensen 19c6689752 Add pgtype.Record and prerequisite restructuring 
Because reading a record type requires the decoder to be able to look up oid
to type mapping and types such as hstore have types that are not fixed between
different PostgreSQL servers it was necessary to restructure the pgtype system
so all encoders and decodes take a *ConnInfo that includes oid/name/type
information.

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.

Jack Christensen 743b98b298 Name PG types as words 
Though this doesn't follow Go naming conventions exactly it makes names more

TidOid. In addition this is one less breaking change in the move to V3.
