postgresHasDefault

Check if default database is available.

Description

RPostgres examples and tests connect to a default database via dbConnect(Postgres()). This function checks if that database is available, and if not, displays an informative message.

postgresDefault() works similarly but returns a connection on success and throws a testthat skip condition on failure, making it suitable for use in tests.

Usage

postgresHasDefault(...)

postgresDefault(...)

Arguments

...

Additional arguments passed on to dbConnect()

Examples

if (postgresHasDefault()) {
  db <- postgresDefault()
  dbListTables(db)
  dbDisconnect(db)
}
