[Beginner Question] How to print the call link graph?

Hi community,
I use the gdb to track the postgres like this:

...

pq_getbyte () at pqcomm.c:980
980     in pqcomm.c
(gdb)  next
985     in pqcomm.c
(gdb)  next
986     in pqcomm.c
(gdb)  next
SocketBackend (inBuf=0x7ffc8f7e1310) at postgres.c:372

372     postgres.c: Directory not empty.
(gdb)  next
403     in postgres.c
(gdb)  next
406     in postgres.c
(gdb)  next
407     in postgres.c
(gdb)  next

...

But the question is:
It's too slow to input 'next' to run the postgres, I used to try to use the  'continut', but the gdb will run the postgres directly and not print the function name and code line

I want to it print like this:

... -> pq_getbyte () at pqcomm.c:980 -> SocketBackend (inBuf=0x7ffc8f7e1310) at postgres.c:372 -> ...

Can someone provide me some advice?
Thanks in advance!

Yours,
Wen Yi
