Hi,
We have API's in /usr/local/pgsql/include/libpq-fe.h which support large
objects in PostGres
extern int lo_open(PGconn *conn, Oid lobjId, int mode);
extern int lo_close(PGconn *conn, int fd);
extern int lo_read(PGconn *conn, int fd, char *buf, size_t len);
extern int lo_write(PGconn *conn, int fd, char *buf, size_t len);
extern int lo_lseek(PGconn *conn, int fd, int offset, int whence);
extern Oid lo_creat(PGconn *conn, int mode);
extern int lo_tell(PGconn *conn, int fd);
extern int lo_unlink(PGconn *conn, Oid lobjId);
extern Oid lo_import(PGconn *conn, const char *filename);
extern int lo_export(PGconn *conn, Oid lobjId, const char
*filename);
My doubt is, do these API's operate on character data? i.e., My table
schema is like this
table (name varchar, script varchar). I have to store a large data(in
character form) in the script column (upto 3 MB).
As of my understanding the above mentioned API's work on the OID field.
i.e,. table(name varchar, script oid). Is that correct?
Please clarify this if anyone has already used this large object APIs and
specify if this has any limitation on the size?
thanks,
-Vadivel
