+.SH "NAME"
+START_TRANSACTION \- start a transaction block
+.SH "SYNOPSIS"
+.sp
+.nf
+START TRANSACTION [ \fItransaction_mode\fR [, \&.\&.\&.] ]
+
+where \fItransaction_mode\fR is one of:
+
+ ISOLATION LEVEL { SERIALIZABLE | REPEATABLE READ | READ COMMITTED | READ UNCOMMITTED }
+ READ WRITE | READ ONLY
+ [ NOT ] DEFERRABLE
+.fi
+.SH "DESCRIPTION"
+.PP
+This command begins a new transaction block\&. If the isolation level, read/write mode, or deferrable mode is specified, the new transaction has those characteristics, as if
+\fBSET TRANSACTION\fR
+was executed\&. This is the same as the
+\fBBEGIN\fR
+command\&.
+.SH "PARAMETERS"
+.PP
+Refer to
+SET TRANSACTION (\fBSET_TRANSACTION\fR(7))
+for information on the meaning of the parameters to this statement\&.
+.SH "COMPATIBILITY"
+.PP
+In the standard, it is not necessary to issue
+\fBSTART TRANSACTION\fR
+to start a transaction block: any SQL command implicitly begins a block\&.
+PostgreSQL\*(Aqs behavior can be seen as implicitly issuing a
+\fBCOMMIT\fR
+after each command that does not follow
+\fBSTART TRANSACTION\fR
+(or
+\fBBEGIN\fR), and it is therefore often called
+\(lqautocommit\(rq\&. Other relational database systems might offer an autocommit feature as a convenience\&.
+.PP
+The
+DEFERRABLE
+\fItransaction_mode\fR
+is a
+PostgreSQL
+language extension\&.
+.PP
+The SQL standard requires commas between successive
+\fItransaction_modes\fR, but for historical reasons
+PostgreSQL
+allows the commas to be omitted\&.
+.PP
+See also the compatibility section of
+SET TRANSACTION (\fBSET_TRANSACTION\fR(7))\&.
