Hi,
In include/catalog/pg_type.h I've noticed the following code.
<Code>
CATALOG(pg_type) BOOTSTRAP
{
NameData typname;
Oid typowner;
int2 typlen;
/*
* typlen is the number of bytes we use to represent a value of this
* type, e.g. 4 for an int4. But for a variable length type, typlen
* is -1.
...
</Code>
The pg_type catalog is then populated with lines like the following.
<Code>
DATA(insert OID = 71 ( pg_type PGUID 1 1 t b t \054 1247 0 foo bar foo bar c _null_));
DATA(insert OID = 75 ( pg_attribute PGUID 1 1 t b t \054 1249 0 foo bar foo bar c _null_));
DATA(insert OID = 81 ( pg_proc PGUID 1 1 t b t \054 1255 0 foo bar foo bar c _null_));
DATA(insert OID = 83 ( pg_class PGUID 1 1 t b t \054 1259 0 foo bar foo bar c _null_));
</Code>
Notice that the type length for types like pg_class have the value of one (1)?
I would have expected them to the same length as an oid.
Am I just seeing things?
Thanks with regards from Maurice
