A shared tcp-check ruleset is now created to support postgres check. This way no
extra memory is used if several backends use a pgsql check.
The following sequence is used :
tcp-check connect default linger
tcp-check send-binary PGSQL_REQ log-format
tcp-check expect !rstring "^E" min-recv 5 \
error-status "L7RSP" on-error "%[check.payload(6,0)]"
tcp-check expect rbinary "^520000000800000000 min-recv "9" \
error-status "L7STS" \
on-success "PostgreSQL server is ok" \
on-error "PostgreSQL unknown error"
The log-format hexa string PGSQL_REQ depends on 2 preset variables, the packet
length (check.plen) and the username (check.username).
