Hi Shrish, The problem appears to be with your PostgreSQL development files under RHEL. The EMBOSS configuration is picking up that your system says it has the development files installed and is including the relevant library that should contain the function 'PQescapeStringConn' i.e. libpq (-lpq). From the error it appears the function isn't there for some reason.
I have not seen this problem on other systems but, as the SQL stuff is a new addition from 6.3.0 I'd be interested to know if people have had similar experiences on non-RHEL machines. I'll likely contact you off-list with a follow-up question. In the meantime, if you cannot update your PostgreSQL then you can always 'make clean' and configure again using: --without-postgresql as your system is reporting that it also has MySQL (which will allow you access to mysql servers [obviously] and the public Ensembl ones).
