[postgis-users] ST_Buffer

[Ed Linde]

Hi,

If I have a linestring which is in srid = 4326, how can I compute the
ST_Buffer so that I have 2m on each side of the line?
I mean SRID 4326 is in degrees, so how can I make the query return me a
buffer around the linestring which has 2m radius?
Do I first convert to geography and then compute the buffer? and then
convert back to geometry?

Thanks,
Ed
