Here results of what I've done.
Just a note all this was done on 7.4.16:
First of all problems:
1. cannot complete configure on flass drive
./configure --prefix=/media/sda1/app/psql/postgresql-7.4.16/bin
--without-readline
...
configure: creating ./config.status
config.status: creating GNUmakefile
config.status: creating src/Makefile.global
config.status: creating src/include/pg_config.h
config.status: linking ./src/backend/port/tas/dummy.s to
src/backend/port/tas.s
ln: creating hard link `src/backend/port/tas.s' to
`./src/backend/port/tas/dummy.s': Operation not permitted
config.status: error: cannot link src/backend/port/tas.s to
./src/backend/port/tas/dummy.s
configure: creating ./config.status
config.status: creating GNUmakefile
config.status: creating src/Makefile.global
config.status: creating src/include/pg_config.h
config.status: linking ./src/backend/port/tas/dummy.s to
src/backend/port/tas.s
ln: creating hard link `src/backend/port/tas.s' to
`./src/backend/port/tas/dummy.s': Operation not permitted
config.status: error: cannot link src/backend/port/tas.s to
./src/backend/port/tas/dummy.s
2.Then I build the source in knopixx directory. Build was
successfull.
An attempt to init database on flash drive failed:
knoppix@Knoppix:/ramdisk/home/knoppix/test/build/bin$ ./initdb -D
/media/sda1/app/psql/rdata
The files belonging to this database system will be owned by user
"knoppix".
This user must also own the server process.
The database cluster will be initialized with locale C.

initdb: removing data directory "/media/sda1/app/psql/rdata"
knoppix@Knoppix:/ramdisk/home/knoppix/test/build/bin$
However I made it work.
Here the work around:
=====================
tar build and data directories and copied over to flash drive. and
when knopix starts I copied it in any directory and it works
restart knopixx
untar data.tar and build.tar into the same directory (just to make it
easy)
Let's try to run:
knoppix@Knoppix:~/db/build/bin$ psql test
psql: error while loading shared libraries: libpq.so.3: cannot open
shared object file: No such file or directory
knoppix@Knoppix:~/db/build/bin$
Opps! missing library, fixing it by setting LD_LIBRARY_PATH. Since
the old value not (in my case) set doing it like this:
knoppix@Knoppix:~/db/build/bin$ export
LD_LIBRARY_PATH=/ramdisk/home/knoppix/db/build/lib
knoppix@Knoppix:~/db/build/bin$ psql test
Welcome to psql 7.4.16, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit
test=# \d
List of relations
Schema | Name | Type | Owner
--------+------+-------+---------
public | the | table | knoppix
(1 row)
test=# select * from the;
name
-------
abcde
(1 row)
test=# \q
knoppix@Knoppix:~/db/build/bin$
Note: The table was create before and was a part od data directory.
TA-DA! It works!!!
the build and data didn't took much space:
2718136 data.tar
14919680 build.tar
OS used: Knopixx 2007-01-04
Kernel: Linux Knoppix 2.6.19
PC Memory 512 MB
This is good enough in my case I probably will re-burn knoppix CD to
include those two tar files - just need to find how, but this is a
different story.
It loos like tar-ing data directory does the work for keeping data
stored back to flash drive, however pg_dump is also can be used.
So, the only problem I had was with creating links and if anybody has
an idea how it can be fixed, can you let me know.
Cheers!
