New returns a new Logger that has this logger's context plus the given context

Scan MUST check r.Type().DataType and r.Type().FormatCode before decoding. It should not assume that it was called on the type of value.

Type returns the *FieldDescription of the value

QueryRow delegates to the underlying *Conn

Check for an error in the last call and if an error has occurred, retrieve the error message from the database environment

Len returns the number of unread bytes

It is like DateErr but return 0000-00-00 if conversion is impossible.

Execute the statement.

prints with log.Printf the C-call trace

Err() returns the reason the connection was closed. It is not safe to call this function until l.Notify has been closed.

SetHandler updates the logger to write records to the specified handler.

Assumes len(*m) is > 5

Benchamrks

It is like DurationErr but return 0 if conversion is impossible.

Get the nn-th value and return it as int. Return 0 if value is NULL or conversion is impossible.

Name returns a more human friendly rendering of the error code, namely the "condition name". See http://www.postgresql.org/docs/9.3/static/errcodes-a

Release gives up use of a connection.

Stat returns connection pool statistics

Do a simple query to ensure the connection is still usable

Acquire takes exclusive use of a connection until it is released.

Create a new cursor (statement) referencing the connection.

ReadString reads count bytes and returns as string

fatal tells r that a Fatal error has occurred

RowsAffected returns the number of rows affected. If the CommandTag was not for a row affecting command (such as "CREATE TABLE") then it returns 0

Log a message at the given level with context key/value pairs

Fatal signals an error occurred after the query was sent to the server. It closes the rows automatically.

recv1 receives a message from the backend, panicking if an error occurs while attempting to read it. All asynchronous messages are ignored, with the

Append adds a value to qa and returns the placeholder value for the argument. e.g. $1, $2, etc.

Next prepares the next row for reading. It returns true if there is another row and false if no more rows are available. It automatically closes rows

Verify that the external LOB var is still valid.

Close the cursor.

Fetch a single row from the cursor.

FuncHandler returns a Handler that logs records with the given function.

Listen starts listening for notifications on a channel. Calls to this function will block until an acknowledgement has been received from the server.

New returns a new logger with the given context. New is a convenient alias for Root().New
