There seems to be something I'm missing wrt the conbin string. I have a table
here with a simple check constraint:
Table "public.a"
Column | Type | Modifiers
--------+---------+-----------
i | integer |
Check constraints:
"x" CHECK (i = 0)
But when I loop around looking at the constraints the conbin text field has an
empty string in it:
(gdb) p *con
$2 = {conname = {data = "x", '\0' <repeats 62 times>, alignmentDummy =
120},
connamespace = 2200, contype = 99 'c', condeferrable = 0 '\0',
condeferred = 0 '\0', conrelid = 24661, contypid = 0, confrelid = 0,
confupdtype = 32 ' ', confdeltype = 32 ' ', confmatchtype = 32 ' ',
conkey = {26}, confkey = {0}, conbin = {vl_len = 1, vl_dat = ""}, consrc
= {
vl_len = 21, vl_dat = "\001"}}
And when I call pg_get_expr with:
consrc = DirectFunctionCall2(pg_get_expr,
PointerGetDatum(&con->conbin), ObjectIdGetDatum(con->conrelid));
I get:
ERROR: invalid memory alloc request size 4294967294
