+.SH "NAME"
+dblink_build_sql_insert \- builds an INSERT statement using a local tuple, replacing the primary key field values with alternative supplied values

+dblink_build_sql_insert(text relname,
+                        int2vector primary_key_attnums,
+                        integer num_primary_key_atts,

+.fi
+.SH "DESCRIPTION"
+.PP
+\fBdblink_build_sql_insert\fR
+can be useful in doing selective replication of a local table to a remote database\&. It selects a row from the local table based on primary key, and then builds an SQL
+\fBINSERT\fR
+command that will duplicate that row, but with the primary key values replaced by the values in the last argument\&. (To make an exact copy of the row, just specify the same values for the last two arguments\&.)
+.SH "ARGUMENTS"
+.PP
+\fIrelname\fR
+.RS 4
+Name of a local relation, for example
+foo
+or
+myschema\&.mytab\&. Include double quotes if the name is mixed\-case or contains special characters, for example
+"FooBar"; without quotes, the string will be folded to lower case\&.
+.RE
+.PP
+\fIprimary_key_attnums\fR
+.RS 4
+Attribute numbers (1\-based) of the primary key fields, for example
+1 2\&.
+.RE
+.PP
+\fInum_primary_key_atts\fR
+.RS 4
+The number of primary key fields\&.
+.RE
+.PP
+\fIsrc_pk_att_vals_array\fR
+.RS 4
+Values of the primary key fields to be used to look up the local tuple\&. Each field is represented in text form\&. An error is thrown if there is no local row with these primary key values\&.
+.RE
+.PP
+\fItgt_pk_att_vals_array\fR
+.RS 4
+Values of the primary key fields to be placed in the resulting
+\fBINSERT\fR
+command\&. Each field is represented in text form\&.
+.RE
+.SH "RETURN VALUE"
+.PP
+Returns the requested SQL statement as text\&.
+.SH "NOTES"
+.PP
+As of
+PostgreSQL
+9\&.0, the attribute numbers in
+\fIprimary_key_attnums\fR
+are interpreted as logical column numbers, corresponding to the column\*(Aqs position in
+SELECT * FROM relname\&. Previous versions interpreted the numbers as physical column positions\&. There is a difference if any column(s) to the left of the indicated column have been dropped during the lifetime of the table\&.
