Types ¶
type ServerStatus ¶
type ServerStatus byte
ServerStatus indicates the current server status. Possible values are 'I' if idle (not in a transaction block); 'T' if in a transaction block; or 'E' if in a failed transaction block (queries will be rejected until block is ended).
type Version ¶
type Version uint32
Version represents a connection version presented inside the connection header
const ( Version30 Version = 196608 // (3 << 16) + 0 VersionCancel Version = 80877102 // (1234 << 16) + 5678 VersionSSLRequest Version = 80877103 // (1234 << 16) + 5679 VersionGSSENC Version = 80877104 // (1234 << 16) + 5680 )
The below constants can occur during the first message a client sends to the server. There are two categories: protocol version and request code. The protocol version is (major version number << 16) + minor version number. Request codes are (1234 << 16) + 5678 + N, where N started at 0 and is increased by 1 for every new request code added, which happens rarely during major or minor Postgres releases.
