I was trying to call the array_in() function using the
DirectFunctionCall3() interface. It fails as the code in array_in()
tries to refer to fcinfo->flinfo->fnextra where flinfo is set to NULL by
the DirectFunctionCall3() interface. I am not sure if this is a bug or
that we are not supposed to use DirectFunctionCall3 to call array_in.
Anyway, I debugged some array related to queries to find that the
following function sequence is used to call array_in
...
OidInputFunctionCall
InputFunctionCall
...
For the time being I will use this, but can someone clarify if what I
stated above is a problem?
Thanks,
Ashish
