Expand description

Connection string parsing with support for service file and a subset of psql environment variables.

Note: tokio-postgres 0.7.9 introduced a change preventing PGUSER and service configuration to set connection user. The release of tokio-postgres 0.7.10 fix this issue.

Environment variables

  • PGSERVICE - Name of the postgres service used for connection params.
  • PGSYSCONFDIR - Location of the service files.
  • PGSERVICEFILE - Name of the service file.
  • PGHOST - behaves the same as the host connection parameter.
  • PGPORT - behaves the same as the port connection parameter.
  • PGDATABASE - behaves the same as the dbname connection parameter.
  • PGUSER - behaves the same as the user connection parameter.
  • PGOPTIONS - behaves the same as the options parameter.
  • PGAPPNAME - behaves the same as the application_name connection parameter.
  • PGCONNECT_TIMEOUT - behaves the same as the connect_timeout connection parameter.
  • PGPASSFILE - Specifies the name of the file used to store password.
