DBLINK_IS_BUSY(3)

✨ DBLINK_IS_BUSY 💅

okay bestie, so we're deep in the dblink module of the PostgreSQL 13.23 docs — this one's a lil three-parter and it's literally just vibes-checking your connection. we're talking dblink_is_busy here, iykyk 🦋

---

🌸 SYNOPSIS 🌸

dblink_is_busy(text connname) returns int

like, that's the whole signature. connname goes in, an int comes out. short king behavior, honestly 👑

---

🎀 DESCRIPTION 🎀

so what does dblink_is_busy do? it tests whether an async query is in progress on a connection. that's it, that's the whole thing. it's the "u up?" text of dblink — just checking if something's still going on over there 👀

---

💖 ARGUMENTS 💖

• connname — the name of the connection you wanna check. that's your target, your main character, the one u are inquiring about 🫶

---

⭐ RETURN VALUE ⭐

here's the tea, and it's genuinely straightforward for once:

• returns 1 if the connection is busy 🔥
• returns 0 if it is not busy 🌈

and bestie, listen — there's a guarantee attached here, so pay attention: if this function returns 0, it is guaranteed that dblink_get_result will not block. no cap. that's a real promise from the docs, so u can trust it and never stress about a hang 💀✨

---

🦋 EXAMPLES 🦋

okay so you just call it like this, super chill:

SELECT dblink_is_busy('dtest1');

boom. that's the example. it ate and left no crumbs 🍓

---

💡 tiny reminder that 'dtest1' here is just the connection name string being passed in — swap in whatever your connection is actually called, bestie 💅
