You can easily do this with JEQL.

A script to read a shapefile and load it into PostGIS would look like
the following. You can choose whatever columns you want to load by
giving their names.
====================================================
ShapefileReader tbl file: "data.shp";
cities = SELECT CITY_ID, NAME, MAPLABEL, SHADE, Shape_area, Shape_len,
Geom.toWKT(GEOMETRY) AS geom FROM tbl;
DbWriter cities
class: "org.postgresql.Driver"
url: "jdbc:postgresql://host:1111/db-instance"
user: "user"
password: "pwd"
sql: $"INSERT INTO Cities (
CITY_ID,NAME,MAPLABEL,SHADE,Shape_area,Shape_len,geom ) VALUES
(?,?,?,?,?,?,ST_GeometryFromText(?,2927))"
batchSize: 1000
commitSize: 1000;
====================================================

I have many shapefiles that are conceptually identical in structure,
except a couple of columns in each file are named differently. These
columns are unimportant.
How can I load all these files in the same table without the offending columns?
# generate the create table and insert commands
shp2pgsql -s 4269 -c file1 table > load.sql
# generate the insert commands for subsequent files
shp2pgsql -s 4269 -a file2 table >> load.sql
shp2pgsql -s 4269 -a file3 table >> load.sql
..
The above commands generate INSERT statements like so --
INSERT INTO "table" (
"area",
"perimeter",
"file1_",
"file1_i",
the_geom
) VALUES (
'2.29080994500086E-04',
'6.34477469815224E-02',
'0106000020AD100000010000000103000020AD100000010000000D000000A4552DE928EA55C0C6F99B5088443E404582A966D6E955C050C8CEDBD8443E40187D0569C6E955C02B508BC1C3443E403DEFC682C2E955C0BB4560AC6F443E40EB8D5A61FAE955C0A6D24F38BB413E402907B30930EA55C0503750E09D403E40C28A53AD85EA55C0A8716F7EC3403E403D997FF44DEB55C058FFE7305F423E402C4833164DEB55C00F4240BE84423E40DAAD65321CEB55C0AFCF9CF529433E40D48041D2A7EA55C046274BADF7433E40FB58C16F43EA55C045F295404A443E40A4552DE928EA55C0C6F99B5088443E40'
);
I don't want file1_ and file1_i and their corresponding values. Is
there a way to specify which columns to load?
