front ends for postgres under linux

Hi,

We have recently shifted our SCO Unix server to Red Hat Linux 6.2 server.
Currently we are running all our SCO applications like Financial
Accounting, PF Accounting, Payroll etc. using ibcs module of Linux.
The applications on SCO were developed using Integra RDBMS.

Now we want to start developing and slowly converting those applications
on Linux platform. For that we have selected Postgresql as the Database.
However we are finding it difficult to decide about the front-ends.

The main problems while choosing the front-ends we encounter is the data
entry part of Master-Detail transactions such as Invoice Entry / Voucher
Entry where there might be variable amount of entries. We thought of
developing under PHP4. But the problem which I have mentioned seems to
remain if we use PHP4.

I wanted to know what the listers are using as front-ends on Linux
platform. Is using PHP4 good enough for developing financial accounting
& inventory applications.

Awaiting to hear your experiences front-ends for Postgers.

Thanks in advance.
