You have to display the PostgreSQL license text in the source code or 
the binary, depending on what you ship.  A strict interpretation would 
say that considering the combined work, this is an additional 
requirement on top of the [L]GPL, so it is not allowed by the terms of 
the [L]GPL.  (But it is allowed by the terms of the PostgreSQL 
license.)  A looser interpretation would say that what the PostgreSQL 
license text says is essentially a subset of what the [L]GPL already 
says anyway, so adding the requirements of the PostgreSQL license on 
top of it does not actually impose additional requirements, so there is 
no problem.  Which one of these interpretations you believe is between 
you and the copyright holders of that LGPL'ed work, but the PostgreSQL 
copyright holders don't care.
