Re: psql command failing with error "undefined symbol: PQhostaddr"

Hey Team,
Thanks for quick responses. But yeah, seems on my system Libpq.so* files were not present in the usual library path. After setting LD_LIBRARY_PATH to consider the location about libpg.so*, the psql  command started working.
thanks,

Hi Team
When I use psql to connect a pg server, I am getting below error. Any solution/pointers?
I have pg versions 11,12,13 installed on my system.

/usr/lib/postgresql/13/bin/psql: symbol lookup error: /usr/lib/postgresql/13/bin/psql: undefined symbol: PQhostaddr

Looks like a bad (too old) version of libpq library.
