ST_LineFromShape

ST_LineFromShape takes a binary column and returns a linestring column. The input binary column must contain the shapefile representation of linestring geometries. You can optionally specify a spatial reference for the result linestring column. The sr parameter value must be a valid SRID or WKT string. If a linestring cannot be created from the input binary the function will return null.
