--> Hi,
-->
--> I am sory for my bad English :)
-->
-->
--> We try to use PostgreSQL on an Embeded System.
-->
--> Plan to use this PC/104 Module
--> http://www.icop.com.tw/products_detail.asp?ProductID=106
-->
-->
--> and this EmbedDisk
--> http://www.icop.com.tw/products_detail.asp?ProductID=185
-->
-->
--> There is a Linux version (X-Linux) for the PC/104 Module.
--> http://www.dmp.com.tw/tech/os-xlinux/
-->
--> This Linux looks enough for our project.
-->
--> We instal X-Linux on PC/104 Module.
-->
--> Now, We want to install PostgreSQL
-->
--> but there are some problems
-->
--> 1 - Firstly,  Can we install PostgreSQL on this X-Linux?
-->
--> 2 - Our EmbedDisk capacity is 128 Mb.
-->     X-Linux size approximately 32Mb.
-->
-->     Our expectation, PostgreSQL operate standart query on basic tables
-->     and listen 5432 port.
-->
-->     A program collect data from peripheral devices, insert this data
-->     into PostgreSQL database. Another program access this database by use
 5432 -->     port, read and delete data.
-->
-->     We want to use PostgreSQL on PC/104 Module  because we already use
-->     PostgreSQL for other part of the project.
-->
-->     We have a capacity problem, so PostgreSQL installation and
-->     database tables must be configure to smaller size.
-->
-->     How can we do this? suggestion,information, document...
-->
-->     How much the PostgreSQL installation size?
-->
-->
-->     Thanks,
-->

--> TIP 3: Have you checked our extensive FAQ?
-->
-->                http://www.postgresql.org/docs/faq

From the 7.4.6 documentation:
Also check that you have sufficient disk space. You will need about 65 MB for 
the source tree during compilation and about 15 MB for the installation 
directory. An empty database cluster takes about 25 MB, databases take about 
five times the amount of space that a flat text file with the same data would 
take. If you are going to run the regression tests you will temporarily need 
up to an extra 90 MB. Use the df command to check for disk space.

This includes space required for compiling the application. Looks like about 
40 MB for the installation and an empty cluster.
