Gapfilling and interpolation

This section contains functions related to gapfilling and interpolation. You can use a gapfilling function to create additional rows of data in any gaps, ensuring that the returned rows are in chronological order, and contiguous. For more information about gapfilling and interpolation functions, see the hyperfunctions documentation.

Some hyperfunctions are included in the default TimescaleDB product. For additional hyperfunctions, you need to install the Timescale Toolkit PostgreSQL extension.
