SPI_FREETUPTABLE(3)

πŸ“¦ version 17.11, in opensuse-leap 16.0

πŸ’… SPI_FREETUPTABLE(3) πŸ’…

okay so this is the SPI_freetuptable page from the PostgreSQL 17.11 Documentation β€” yes bestie, the big SPI_FREETUPTABLE(3) manual entry, we're reading it together, grab a snack πŸ“


✨ NAME ✨

SPI_freetuptable β€” frees a row set that was created by SPI_execute or a similar function πŸ§ΉπŸ’–


✨ SYNOPSIS ✨

void SPI_freetuptable(SPITupleTable * tuptable)

that's it. that's the whole signature. no cap. 🫢


✨ DESCRIPTION ✨

okay so SPI_freetuptable frees a row set that was made by an earlier SPI command execution function, like SPI_execute. and the way that it's so common to just pass the global variable SPI_tuptable as the argument β€” literally iconic behavior, everybody does it πŸ’…

this function is genuinely useful if your SPI-using C function needs to execute multiple commands and does not want to keep the results of earlier commands hanging around until it ends. like, let it go, bestie. πŸ¦‹

but fr fr, note this: any unfreed row sets will be freed anyway at SPI_finish. so you're not dooming anything by forgetting β€” it's just tidier.

also (and this is the part where the plot thickens 🌸): if a subtransaction is started and then aborted within the execution of an SPI-using C function, SPI automatically frees any row sets that were created while that subtransaction was running. so that's handled for you, king πŸ‘‘

and here's the glow-up lore ✨ β€” beginning in PostgreSQL 9.3, SPI_freetuptable contains guard logic to protect against duplicate deletion requests for the same row set. in previous releases? duplicate deletions would lead to crashes πŸ’€ so yeah, we love a guard rail. periodt.


✨ ARGUMENTS ✨

  • SPITupleTable * tuptable β€” pointer to the row set you want to free, or NULL to do absolutely nothing (respect the nothingness πŸ™ˆ)

πŸŽ€ tiny vibe check reminder: NULL = no-op, not an error. she's unbothered.

and that's the page!! mwah πŸ’‹ this was the SPI_freetuptable entry, served to you courtesy of PostgreSQL 17.11, dated 2026 β€” go free those tuple tables, bestie, you got this πŸŒˆπŸ‘‘πŸ’œ
