@spec display_settings() :: [String.t()]

Configuration settings that affect formatting of values of certain types.

These settings should be set for the current session before executing any queries or statements to safe-guard against non-standard configuration being used in the Postgres database cluster or even the specific database Electric is configured to connect to.

The settings Electric is sensitive to are:

• bytea_output - determines how Postgres encodes bytea values. It can use either Hex- or

                     Escape-based encoding.copy

• DateStyle - determines how Postgres interprets date values.

• TimeZone - affects the time zone offset Postgres uses for timestamptz and timetz values.

• extra_float_digits - determines whether floating-point values are rounded or are encoded precisely.

• IntervalStyle - determines how Postgres interprets and formats interval values.
