Solution 1 : For solving this you need to open and edit pg_hba.conf, where you need to replace all peer with md5. Psql: FATAL: Peer authentication failed for user “postgres” Problem 1 : While running query or fetching shapefile table in postgresql I got the following error: Problems and solution encountered in implementing Import shapefile in postgresql
Lets now look over the problem and solution for the same, if you are also facing the same. While I have faced few problems while importing shapefile and checking the shapefile table in postgresql. This will show all rows and column in table format. This will navigate you in database you created. Now to know the attributes details of the table you can run following query: Lets get connect with postgresql database. Know the details of shapefile inserted in postgresql or postgis Nybb.shp is the shapefile, nybb is the database table name, hello is the database user which is replace byDATABASE_USER and gisdata is the database. Here 2263 is spatial reference system or coordinate system of the shape file. Shp2pgsql -I -s 2263 nybb.shp nybb | psql -U hello -d gisdata Shp2pgsql -I -s 2263 SHAPEFILE.shp DATATABLE | psql -U DATABASE_USER -d DATABASE_NAME Just navigate yourself to unzipped folder and execute the given command

The structure of table should be in this format, which should have a geom as Geometry column atleast.ĬREATE TABLE TABLE_name(gid integer, code smallint, name varchar(32), shape_leng numeric, shape_area numeric, geom geometry) ĬREATE TABLE nybb(gid integer,code smallint, name varchar(32),shape_leng numeric,shape_area numeric,geom geometry) shp2pgsql command to import shapefile SSL connection (protocol: TLSv1.2, cipher: ECDHE-RSA-AES256-GCM-SHA384, bits: 256, compression: off) Psql -h localhost -U DATABASE_USER DATABASE_NAME Now test created database is working properly by executing the given command Sudo -u postgres createdb -O DATABASE_USER DATABASE_NAME Now lets create one database using given command as: Now to import shape file you first need to create database and table. Creating database and table in postgresql before inserting the shapefile You can choose any other shape file which contain atleast this 3 files i.e. For instance to demonstrate import shapefile in postgresql, I have downloaded United state administrative boundary shape file.

If you don’t have any such shapefile, you may download the shapefile for free as suggested in the linked post.
Import Shapefile in Postgresqlįor inserting shapefile to postgis, we first need to have one shapefile. If shp2pgsql is not installed, you should first download the same from the authentic website and then try to follow out the steps provided below. If you are linux or ubuntu system, you can check the same by running shp2pgsql command in terminal after navigating to “/usr/lib/postgresql” path. What does shp2pgsql command does? shp2pgsql is a command line tool, which helps in to convert or import single or multiple shapefiles into postgresql or postgis database tables. Also for running a command line tool to import shapefile you should check if shp2pgsql is available in your system and is installed.

Prior to import Shapefile in Postgresql, we first need to install postgresql and PostGIS. Similarly you may also check for exporting shapefile from postgresql database. This makes developer to think for importing the shapefile data in postgresql and view attributes.
As shapefile is just a representation of Geo Data, while postgresql is database which support many GIS functionalities as like finding nearest neighbour, distance calculation from one point to another etc. PostGreSql Database support Spatial or GIS data.
Shapefile is a data vector file, which stores GeoSpatial Data. Import Shapefile in Postgresql directly by command line tool.
