postgresql

postgresql is the PostgreSQL wire protocol. The target is host:port (default 5432). The step sends and receives raw bytes as hex, and the session persists across steps, so a solution can stage an exchange and continue it.

Fields

postgresql uses the byte-session fields from tcp:

field	required	what it does
send	yes	the bytes to send, as hex or hex "text"; empty when a step only reads
recv		how many bytes to read at most
recv_until		stop reading once this hex marker appears
timeout		how long to wait, in seconds
close		end the session after this step
capture		pull a value out of the received hex for later steps

Example

postgresql ssl-request
  meaning: request an SSL connection and look for the single-byte response
  send: 0000000804d2162f
  recv: 1
  assert: contains "53"
