Here is my problem and also the question. I'd like adding a field in Path structure and Plan structure as follows:
typedef struct Path{ ....bla bla bla Cost energy_cost; ....bla bla bla } typedef struct Plan{ ....bla bla bla Cost energy_cost; ....bla bla bla } Also, I have modified the funscopy.c and every related place where the other field total_cost appears. Right now, the compile is fine and build is fine. However, everytime the server is running and I send a query to the server, it crashed. as psql:1.sql:23: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. psql:1.sql:23: connection to server was lost Is there anyone who can help me with it?
