I have postgresql7.4.6 runing . I am not able to log into database

getting the following error for both

psql: relocation error: psql: undefined symbol: get_progname

createdb: relocation error: createdb: undefined symbol: get_progname

It seems you are mixing programs and libraries from different

which libpq library the programs are actually using and check if that
is the right version.
