Set or Get taskqueue Options

Configure or retrieve database connection parameters for taskqueue. Options are typically set via environment variables in .Renviron, but can be overridden programmatically.

Usage

taskqueue_options(...)

Arguments

...: Option names to retrieve values (as strings), or key=value pairs to set options. All option names must be specified.

Value

If no arguments: list of all option values. If argument names only: list of specified option values. If setting values: invisibly returns updated options.

Details

By default, options are read from environment variables set in ~/.Renviron. Use this function to override defaults temporarily or check current settings.

Changes are session-specific and don't modify environment variables.

Supported options

host: PostgreSQL server hostname or IP address (from PGHOST)
port: PostgreSQL server port, typically 5432 (from PGPORT)
user: Database username (from PGUSER)
password: Database password (from PGPASSWORD)
database: Database name (from PGDATABASE)
