pgsql2shp - postgis to shapefile dumper
Contents
Description
The pgsql2shp table dumper connects directly to the database and converts a table (possibly created by
user query) into a shape file. It is compatible with all versions of PostGIS.
Version: 1.1.5 (2006/10/06)
Examples
An example session using the dumper to create shape file from a database might look like this:
# pgsql2shp-fmyfile-p5555my_dbroads_tableInstallation
To compile the program from source, simply run "make" in the source directory. Then copy the binary in
your shell search path (or wherever you like). This text is also available as a man page in the
../doc/man/ directory, ready for copying it into the manual search path on unixoid systems.
Name
pgsql2shp - postgis to shapefile dumper
Options
The commandline options are:
-f <filename>
Write the output to a particular filename.
-h <host>
The database host to connect to.
-p <port>
The port to connect to on the database host.
-P <password>
The password to use when connecting to the database.
-u <user>
The username to use when connecting to the database.
-g <geometrycolumn>
In the case of tables with multiple geometry columns, the geometry column to use when writing the
shape file.
-b Use a binary cursor. When used on pre-1.0.0 PostGIS versions this will reduce the likelihood of
coordinate drift due to conversion to and from WKT format. Coordinate drifts will not occur with
PostGIS 1.0.0 and newer versions. It will be slightly faster, but might fail if any NON-geometry
column lacks a cast to text.
-r Raw mode. Do not drop the gid field, or escape column names.
-d For backward compatibility: write a 3-dimensional shape file when dumping from old (pre-1.0.0)
postgis databases (the default is to write a 2-dimensional shape file in that case). Starting from
postgis-1.0.0+, dimensions are fully encoded.
-k Keep identifiers case (don't uppercase field names).
-m <filename>
Specify a file containing a set of mappings of (long) column names to 10 character DBF column
names. The content of the file is one or more lines of two names separated by white space and no
trailing or leading space:
COLUMNNAME DBFFIELD1\n
AVERYLONGCOLUMNNAME DBFFIELD2\n
etc.

Syntax
pgsql2shp [options] database [schema.]table
pgsql2shp [options] databasequeryUsage
The <database> is the name of the database to connect to.
The <table> is the (optionally schema-qualified) table to read spatial data from. Alternatively, you can
specify a QUERY whose result will be written into the shapefile.
