.SH "NAME"
ALTER_CONVERSION \- change the definition of a conversion
.SH "SYNOPSIS"
.sp
.nf
ALTER CONVERSION \fIname\fR RENAME TO \fInew_name\fR
ALTER CONVERSION \fIname\fR OWNER TO { \fInew_owner\fR | CURRENT_USER | SESSION_USER }
ALTER CONVERSION \fIname\fR SET SCHEMA \fInew_schema\fR
.fi
.SH "DESCRIPTION"
.PP

\fBALTER CONVERSION\fR
changes the definition of a conversion\&.
.PP
You must own the conversion to use
\fBALTER CONVERSION\fR\&. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have
CREATE
privilege on the conversion\(aqs schema\&. (These restrictions enforce that altering the owner doesn\(aqt do anything you couldn\(aqt do by dropping and recreating the conversion\&. However, a superuser can alter ownership of any conversion anyway\&.)
.SH "PARAMETERS"
.PP
\fIname\fR
.RS 4
The name (optionally schema\-qualified) of an existing conversion\&.
