Hallo,
I found a problem making new data type kata,expecially
when make the C file ,can anyone help me solve it.
This error occur when I'm compiling the C file :
/usr/lib/gcc-lib/i586-suse-linux/3.3.1/../../../crt1.o(.text+0x18):
In function `_start':
../sysdeps/i386/elf/start.S:98: undefined reference to
`main'
collect2: ld returned 1 exit status
You don't have a main() function. This is the function that gets called
when you run an executable. Looking at your code, it seems like you want
to produce a library rather than a standalone program.
This might help:

Also, read the section on C-language functions in the manuals.
Also, you're clearly missing bound-checking on your various copy
operations, and I think you're supposed to use palloc() rather than
malloc() if this is supposed to sit inside PostgreSQL.
Bear in mind it's been 10 years since I wrote any C though, so use your
own judgement on my advice.
