Hi Dilip,


Thanks for your response.



The steps you followed are right. May i know in which OS you tried? Mac/Linux.



Because,  In Mac, it is working fine. just as expected. But the 
problem(segmentation fault) i'm facing is with linux systems.



Thanks & Best Regards,

-Mahi

I did not see the code but just tested with your code. 

 

1) Added test_dsa to shared preload library. 

2) CREATE EXTENSION test_dsa; 

3) executed test_dsa_data_access(1) 

 

postgres=# select test_dsa_data_access(1);

 test_dsa_data_access

I don't see any segmentation fault. Is there some other step which I 

have missed.
