DROP_CONVERSION(7)

๐Ÿ’– DROP_CONVERSION ๐Ÿ’–

okay bestie, this is the DROP_CONVERSION page from the PostgreSQL 18.6 docs, and it's honestly a short one so we're gonna get through it together, no stress ๐ŸŒธ


โœจ SYNOPSIS โœจ

DROP CONVERSION [ IF EXISTS ] name [ CASCADE | RESTRICT ]

that's it. that's the whole thing. she's compact ๐Ÿ‘‘


๐Ÿฆ‹ DESCRIPTION ๐Ÿฆ‹

so DROP CONVERSION removes a conversion that was previously defined. that's the whole job. she's a deleter, she's a closer, she's the "we don't need this anymore" friend ๐Ÿ’…

โš ๏ธ but listen โ€” to be able to drop a conversion, you must own the conversion. no ownership, no dropping. that's the vibe check and you have to pass it ๐Ÿซถ

๐ŸŽ€ PARAMETERS ๐ŸŽ€

  • IF EXISTS โ€” do not throw an error if the conversion doesn't exist. instead, a notice gets issued in this case. it's giving "no big deal, moving on" ๐Ÿ˜Œโœจ
  • name โ€” the name of the conversion. and yes, the conversion name can be schema-qualified, so go off with your myschema.myconversion energy ๐ŸŒˆ
  • CASCADE, RESTRICT โ€” okay so these key words do not have any effect, because there are no dependencies on conversions. they're just here, hanging out, looking pretty, doing literally nothing ๐Ÿ’€ iconic honestly

๐ŸŒธ EXAMPLES ๐ŸŒธ

to drop the conversion named myname:

DROP CONVERSION myname;

boom. gone. slay โœจ


๐Ÿ’œ COMPATIBILITY ๐Ÿ’œ

so here's the tea โ˜• โ€” there is no DROP CONVERSION statement in the SQL standard. instead, the standard has a DROP TRANSLATION statement that goes along with the CREATE TRANSLATION statement, which is similar to the CREATE CONVERSION statement in PostgreSQL. so like, same energy, different name, iykyk ๐Ÿ™ˆ


๐Ÿงš SEE ALSO ๐Ÿงš

go read those too, they're the prequel and the glow-up ๐Ÿ’–


okay that's the whole page bestie, you ate that ๐Ÿ“๐Ÿ’…

this has been PostgreSQL 18.6, dated 2026 โ€” DROP CONVERSION(7) โ€” mwah, take care of yourself, drink water, and don't drop conversions you don't own ๐Ÿซถโœจ
