   Assuming with "root" access you mean "DB-superuser" rights.
   No way!
   From  the  C language, he has total access to the DB backend,   running under the OS-side database system  owners
UID. That   means,   he   has   complete  OS  access  to  the  entire  DB   installation! He could read/write system
catalogswithout any   permission  checks (SPI is only for convienience, someone can   use heap-am as well).
 
   So in fact, he IS  a  superuser  then.  And  that  should  be   reflected  in  his  rights.  Giving  him the right
wouldalso   prevent him from doing stupid things to gain access for  data   he shouldn't have, possibly corrupting you
DBinstallation by   accident.
 
   If that all isn't an option for you,  give  him  his  own  DB   installation  where  he  is  his  own superuser.
Therehe can   develop those things and after code revision, you install the   modules in the production system.
