psql wishes or even realized?

Hello,
I am new here and want to give some informations about me:
I'm using postgreSQL 7.2.1 on Linux and in future on Netware and I am developing with Delphi and administrate some
servers. 

I am using postgreSQL since about 5 weeks, but I have used this time to design my database and since yesterday, I
createit. 
I am not a friend of pgadmin, because something was wrong and so I couldn't add more tables. So I've decided to use
psql.
Everything is working fine with the creation of the tables, but I have two things, which could be better:

1) sql-logfile of psql
after I have created some tables , I can't remember exactly the sql-code, if I have done everything correctly and so, I
amsearching the possibility to get a file, where all SQL-code is beeing listed, I've written with psql (to make a
TQuerywith Delphi to create the same database by clicking on a simple button) 

2) better implementation of cursor-keys
if I have done an error in a line, I can't go to this line and fix it, because I get letters like ^[[D. How is this bug
tofix? I'm using the german keytable.  

Thank you very much
Daniel Seichter
