func (*Postgres) WriteFormattedTime added in v1.1.8

func (pd *Postgres) WriteFormattedTime(buf common.BufferWriter, t time.Time)

WriteFormattedTime formats t into a format postgres understands. Taken with gratitude from pq: https://github.com/lib/pq/blob/b269bd035a727d6c1081f76e7a239a1b00674c40/encode.go#L403

func (*Postgres) WriteReflectedType added in v1.2.0

func (pd *Postgres) WriteReflectedType(buf common.BufferWriter, t interface{})

WriteReflectedType will write a Postgres-specific type name based on a primitive type given by r

func (*Postgres) WriteStringLiteral

func (pd *Postgres) WriteStringLiteral(buf common.BufferWriter, val string)

WriteStringLiteral writes an escaped string. No escape characters are allowed.

Postgres 9.1+ does not allow any escape sequences by default. See http://www.postgresql.org/docs/9.3/interactive/sql-syntax-lexical.html#SQL-SYNTAX-STRINGS-ESCAPE In short, all backslashes are treated literally not as escape sequences.

type SQLType added in v1.2.0

type SQLType interface {
	SQLType() string
}

SQLType is called by WriteReflectedType before any other conversion is considered. This allows for types which implement Scan/Value to also provide their own SQL type name
