 From here:

https://www.postgresql.org/docs/current/libpq.html

"libpq is the C application programmer's interface to PostgreSQL. libpq 
is a set of library functions that allow client programs to pass queries 
to the PostgreSQL backend server and to receive the results of these 
queries.

libpq is also the underlying engine for several other PostgreSQL 
application interfaces, including those written for C++, Perl, Python, 
Tcl and ECPG. So some aspects of libpq's behavior will be important to 
you if you use one of those packages. In particular, Section 32.15, 
Section 32.16 and Section 32.19 describe behavior that is visible to the 
user of any application that uses libpq."

To me that is, yes it is important.
