Actually, I should explain this a bit further --
(a) I had a Shapefile in USA_Lambert_Conformal_Conic that I imported
into PostGIS using the shp2pgsql, psql dance. Whatever I did, its SRID
is set to -1.
(b) I created another dataset from lon/lat explicitly setting its SRID to 4326.
Of course, now I can't do any geometrical analysis on these two
because they are in different spatial references. Ideally, I want to
convert my (b) dataset, the points that are in 4326, to the same srs
as (a) dataset, namely USA_Lambert_Conformal_Conic.
Hence my question.
Many thanks in advance.
