pgloader question - postgis support

Hi,

I'm looking at pgloader to automate data loading into a Postgis enabled Postgres database.

I have seen in the tutorial how the internal point type is supported, and how the postgis extension can be pre-installed by pgloader if necessary, but I can't see how I might take x & y values & save as a postgis point. I guess I could do this via a trigger, but that is hopefully an unnecessary workaround.

if I read data in (say from CSV):

1,tan0104,1,173.567,-43.678

...

to a Postgis table:

create table station

(id int primary key,

trip char(7)

station_no int,

lon_s decimal(7,4),

lat_s decimal(6,4),

startp geometry(POINT,4326));

the startp column is populated by the SQL:

startp=ST_SetSRID(ST_MakePoint(lon_s,lat_s),4326)

This creates a point feature from the x (lon) & y (lat) coordinates,

and specifies the coordinate reference system as lat/lon degrees WGS84 (EPSG:4326) to match the column specification.

How can I implement that in the pgloader command to load the CSV file?

Thanks
